Elevating Incident Response with the Ultimate Network Forensics

After a successful SOC @ RSAC2025, our team was stoked to be invited to help Cisco run the SOC at Cisco Live US (CLUS). We jumped at the chance to work with the Cisco team again. It was a great opportunity to innovate while helping Cisco protect and educate the attendees of the conference. Plus, the Cisco team is a lot of fun to hang out with—there’s a very infectious vibe in the SOC that has everyone buzzing for the entire week.

Packet capture is essential in the SOC. It provides an indelible record of all network activity, which is invaluable to the SOC team when investigating threats or security risks—hence the phrase, “PCAP or it didn’t happen.” For CLUS, we deployed two EndaceProbes with a combined storage of 864TB to continuously record all network activity delivered via 2 x 10GbE SPAN ports. This gave us the capacity to record at least several weeks of full network packet data—covering more than the entire duration of the show.

Endace Fusion integrations provided the glue between the Cisco Security suite and the packet data on the EndaceProbes, enabling analysts to quickly pivot from Splunk Enterprise Security/Splunk Cloud, Cisco XDR, Cisco Firepower, and Cisco Secure Network Analytics (SNA) through to EndaceVision and hosted Wireshark. When access to historical full PCAP is available in a seamless integration, security analysts are empowered with the ease of contextual access, and this simplifies the use of PCAP data, where previously it could be seen to be cumbersome to use.

The EndaceProbes each hosted two VMs that were running Zeek and delivering critical log data into Splunk. Custom Zeek script additions provided additional valuable detail around clear text passwords in email and HTTP, shining a light on the heavy use of insecure protocols, and ultimately driving automation to manage the unexpected volume. File-carving was enabled, and over 750,000 files were reconstructed from packet data, with over 40,000 samples submitted to Splunk Attack Analyzer (SAA) via Endace’s automatic submission software. SAA then sent over 12,000 files to Secure Malware Analytics (formerly Threat Grid) for dynamic analysis of the behavior.

SOC Findings and Lessons Learned

The SOC team was surprised and initially overwhelmed at the volume of unencrypted traffic on the network. Logging of passwords was coupled with a Cisco XDR automation that created an incident on each detection. This resulted in a heavy workload identifying and notifying users to educate and protect them in the future. The Splunk team developed a creative automated solution to notify users that the SOC detected their use of insecure protocols.

We even found a version of POP that was news to us all—APOP. This hashes the server timestamp in the response header with the user’s password to create a password digest. While this obscures the password, it only delays its inevitable retrieval, all the while the actual message bodies are still transferred in plain text!

In the theme of plain text passwords, reviewing the connections associated with one of these sessions showed a large number of file downloads in the Zeek log generated on EndaceProbe.  This was one of many clients that used the free conference Wi-Fi to download Windows update files, but after filtering out the cab files in a Splunk search, we found a suspicious-looking file:

A search on this filename in SAA confirmed the presence of a malware download by this unfortunate user, whom the SOC team made every effort to identify.

There were also a few notable occasions where Secure Firewall alerts indicated intrusion attempts, which, after a pivot to EndaceVision, were pulled up in Wireshark for further analysis. One alert of note was a “BROWSER-IE Microsoft Internet Explorer Chakra.dll Array.filter type confusion attempt” indicating a malicious web server was trying to exploit a vulnerability in IE. 

A review of the PCAP noted that the target client was, in fact, running Safari on MacOS X.

This indicated that even if the web server was launching a legitimate attack, the client was not vulnerable to this attempt and therefore no further action was required. This highlights the value of full PCAP, packets in related sessions that don’t trigger alerts can offer valuable insight and context to security analysts. This allows rapid determinations to be made with confidence.

Helping Protect Cisco Live 2025 in San Diego

Original Entry by : Michael Morris

By Michael Morris, Senior Director of Technology Alliances

Building on our collaboration in the SOC at RSAC 2025, Endace was honoured to be invited by Cisco to provide EndaceProbe packet capture and a team of threat hunters to support the Cisco Live Security Operations Center (SOC). Our primary goal was to protect the network and attendees at Cisco Live San Diego 2025, our secondary goals were to educate and innovate.

Two EndaceProbes were deployed in Cisco’s SOC-in-a-Box, continuously recording all network traffic provided over two 10G SPAN ports.  We integrated with Splunk Enterprise Security and Cisco Security Cloud to deliver real-time network visibility. This enabled the SOC team to detect, locate, and address threats to attendees from external and internal sources, and helped to streamline and accelerate SOC investigation workflows.

The SOC at Cisco Live aims to protect the more than 23,000 attendees from threats on the conference network. When an attendee’s device is found to be compromised or unsecured, the SOC team makes every effort to identify, locate and help remediate the issue. The SOC team also provided public tours of the SOC to educate attendees about how the SOC is configured, the processes team members implemented, and the sorts of issues and threats that we uncovered.

Drawing on our experience at RSAC 2025 (where Endace captured 36 TB of data and 45 billion packets) we further optimized our approach for Cisco Live’s SOC.

The SOC was set up in two days, leveraging prior planning and our engineers’ experience at RSAC 2025.

At Cisco Live, Endace:

  • Captured 78.9 TB of traffic representing 99.5 billion packets
  • Reassembled more than 740,000 file objects in real time and sent 42,624 files to Splunk Attack Analyzer for further analysis
  • Detected 2,256 occurrences of cleartext passwords being used from 92 unique devices
  • Provided packet-level forensic evidence to all the SOC analysts for investigating and triaging a range of security events
  • Integrated with Cisco XDR, Splunk, Cisco Firepower IDS, Splunk Attack Analyser, Cisco Secure Malware Analytics, Cisco Secure Network Analytics to provide a seamless IR workflow
  • Innovated with new integrations that streamed additional metadata into Splunk, which sped up the investigation and remediation process

It was impressive to see the whole team of Cisco and Endace Engineers pivoting to the packet data to investigate an entire range of security incidents. Inspecting the packet data enabled fast decisions because the team could see exactly what was happening on the wire before, during, and after any event. As they say, PCAP or it didn’t happen!

Having complete packet data available at the SOC team’s fingertips really highlighted the incredible value of always-on packet capture; recording every packet and delivering complete, real-time visibility into threats, performance issues, and anomalous behaviour across the network.

There is an infectious energy that we get when working in a SOC environment like this, with Engineers from different teams and companies collaborating to track down threats, and share ideas on how to improve the SOC. The Endace team came away with many learnings that will improve EndaceProbe and our partner integrations.

We look forward to being a part of the SOC again at some more big upcoming events – stay tuned, details coming soon.

Why everyone should care about FIPS 140, NIAP NDcPP, and DoDIN APL.

Cary Wright, VP Product Management, Endace

Weak security plagues far too many of the IT products we use today. The problem is, there is no unified mandate to compel vendors to invest in security hardening their products. Vendors are free to choose how heavily to invest in security. So it’s no surprise that many vendors don’t invest heavily enough in thoroughly security hardening their products.
 
However, in many industries – such as Government, defense or critical infrastructure – the potential impact of a security vulnerability in a product is just too serious for organizations to leave it to vendors to decide how to secure their products. For this reason, organizations in many of these industries mandate that vendors must submit their products to rigorous testing and certification processes to ensure the security of their products is iron clad.
 
At Endace we found out first-hand how difficult and rigorous these standards are to comply with. The effort took us the better part of a year and significant investment in software development, testing and validation, and certification. Armor plated security is a good way to describe what these standards require. Our recent OSm 7.2.1 release includes everything we had to do to comply with these standards.
 
The good news for customers – regardless of the industry you are in – is that this rigorous testing and validation process doesn’t just benefit Government, Defense and critical infrastructure organizations. Any organization that adopts products that have passed these certification processes can be confident those products have been independently evaluated to minimize the risk of security vulnerabilities and are fit-for-purpose for deployment in high-security environments.
 
By selecting a product with DoD level security compliance you reap the benefit of millions of dollars of investment in security testing and hardening that goes way beyond standard penetration tests and security scans. The testing process for each of these certifications involves delving deep into the product – comprehensive testing, source code reviews, and independent validation that the security controls of the product are robust and well designed.
 
 

What are these standards, and what do they test?

Complying with FIPS 140-3 is the fundamental first step in certification. FIPS mandates that products must use robust and secure encryption. This is not a bolt-on. Products must implement a validated cryptography module as a central software pillar to ensure all encrypted communications meet the NIST standard for strong cryptography, including HTTPS, SSL, and SSH.
 
Just including encrypted HDDs in a system – as some vendors do to claim compliance with FIPS – is not sufficient. Every communication to and from the system must be secured with FIPS validated cryptography before the system can be FIPS certified. Independent testing confirms that products comply with the FIPS standards.
 
NIAP NDcPP 2.2e, also known as Common Criteria, is an international standard agreed by 18 nations. It builds on FIPS to define security requirements that are expected to be implemented by all network devices. It goes extremely deep to validate a product has robust security. By deep, I mean months of extensive testing, inspection, and independent code reviews, conducted and signed off by government signatories who are usually security experts in defense departments.
 
DoDIN APL stands for the US Department of Defense Information Network Approved Products List. With FIPS and NIAP certification in hand and a US DoD sponsor, a vendor’s final step is undergo product testing by a US DoD lab against DoD cybersecurity requirements. Being listed on the APL is the last big stage of a long and intensive project but it’s not the end of the story. Ongoing maintenance and revalidation ensures that a product remains secure throughout its life.

OSm 7.2.1 is released and available for download.

I am very proud of the team at Endace for having delivered a huge release with OSm 7.2.1 . This release has focused on meeting all the requirements for these intensive – but extremely valuable – security standards. And I am glad to say that every Endace customer will benefit from this huge investment in product security hardening.

Cary Wright, VP Product Management, Endace

We’re pleased to announce our newest technical partnership with leading SIEM and observability platform provider, Elastic. By combining together EndaceProbe™ always-on Hybrid Cloud packet capture, Elastic™ Stack and Elastic™ Security, we’re providing the packet-level network visibility and detailed network metadata that Security and IT teams need when responding to security threats and network or application performance issues.

How Do We Work Together?

By combining Endace and Elastic Stack, organizations gain accurate, highly detailed visibility into both real-time and historical network activity. Security and IT analysts can search network metadata in Elastic, and quickly pivot to full packet data for forensic investigations when they need to. The result is faster, more accurate incident investigation and resolution. The combination of Elastic Stack and EndaceProbe gives cybersecurity and IT teams the ability to see exactly what’s happening on their network in real-time. EndaceProbes can record weeks or months of full packet capture across hybrid cloud networks to provide a complete and accurate record of all network activity. The detailed full packet capture data recorded by EndaceProbes is a perfect complement to the rich logs and metadata collected by Elastic Stack. When analysts need to go back-in-time to investigate any incident they have a complete record of that activity at their fingertips. Beyond this, the ability to pivot from anomalies or security alerts directly to forensic examination of packet-level data lets analysts see exactly what’s happening. They can quickly respond to incidents and dramatically mitigate threat risk to their organizations.

EndaceFlow and Elastic Stack

In addition, EndaceProbe appliances can host EndaceFlow™, which generates extremely high-fidelity NetFlow data at full line rate. This NetFlow data can be ingested by Elastic Stack to provide detailed metadata for monitoring the security and performance of the network and interrogating network activity. Pre-built integration between EndaceProbes and Elastic Stack enables streamlined investigation workflows. Analysts can click on alerts in the Elastic UI to go directly to the related full packet data recorded by EndaceProbe. Analysts can quickly view traffic right down to individual packet level to see precisely what occurred before, during and after any event, with absolute certainty.

Scalable Packet Capture for Hybrid Cloud

By Cary Wright, VP Product Management, Endace

Cary Wright, VP Product Management, Endace

The rapid growth of cloud vulnerabilities, hijacked cloud credentials, APTs targeting cloud, and lack of network layer visibility in cloud has made one thing clear: recorded network packet data is just as essential in the cloud as it is in physical networks. 

Enterprises know the value of our packet capture solutions, and they have told us they need the power of packets in the cloud as well. In many cases, they have moved – or plan to move – workloads to the cloud but have been hampered by an inability to gain the same visibility into activity in their public cloud infrastructure as they are used to relying on in on-premise environments.

Leveraging our 20-plus years of experience in delivering accurate, reliable packet capture for some of the world’s largest organizations, Endace developed EndaceProbe Cloud as the first truly scalable, enterprise-class solution for providing always-on packet capture in public cloud environments.

Unlike many solutions on the market, we’ve done it in a way that scales easily and delivers truly unified visibility that lets security, network and IT teams analyze packet data from across hybrid cloud and multi-cloud environments quickly and easily from a central console. 

EndaceProbe Cloud delivers packet-level visibility for public cloud that is critical for threat hunting, incident response and performance management in those environments. It operates seamlessly with EndaceProbe hardware appliances to deliver always-on packet capture across on-premise, private and public cloud infrastructure, to provide unified visibility across the entire network.

See it in Action

The demo below shows how easy it is to quickly search for packet data across a multi-cloud – AWS and Azure – environment, recreate files from packet data and drill-in to analyze the full packets. All from a single console.

EndaceProbe Cloud is a full-featured EndaceProbe, purpose-built for deployment in AWS and Microsoft Azure environments that provides the following benefits to customers in cloud and hybrid cloud environments:  

    • Continuous, zero-loss, packet capture in public and hybrid cloud environments that provides weeks or months of visibility 
    • A unified console for fast global search and analysis across on-premise, private and public cloud environments.  
    • Full visibility into North-South and East-West traffic 
    • Secure packet storage within the customers’ own virtual network or virtual private cloud (VPC). 
    • Powerful traffic analysis and investigation tools including file extraction, log generation, and hosted Wireshark™ 
    • Seamless workflow integration with an open API and strong ecosystem of third-party network and security tools (https://www.endace.com/fusion-partners) 
    • Subscription-based pricing that offers flexibility and scalability  

EndaceProbe Cloud complements Endace’s hardware appliances to provide unified and seamless visibility across the entire network.

Multi-Tenancy introduced with OSm 7.1

Original Entry by : Cary Wright

Securely sharing packet capture infrastructure across multiple entities

By Cary Wright, VP Product Management, Endace

Cary Wright, VP Product Management, EndaceWe are proud to announce that EndaceProbe now supports Multi-Tenancy, “Woo-hoo” I hear you say! If you are an MSPP, MDR, Service Provider, or organisation with multiple departments, your SoC teams can now reap the benefits of having access to weeks or months of continuously recorded network traffic whilst sharing costs with many other likeminded SoC teams. Let’s dig into what Multi-Tenancy is and why it’s important.

At the most basic level, Multi-Tenancy is the ability to host multiple “entities” (e.g. multiple customers or multiple organizational divisions) on a single architecture at the same time. To put it another way, Multi-Tenancy offers a way to share the costs of a system or service across more than one entity. Multi-tenancy can mean different things depending on your domain of expertise:

  • Cloud providers are inherently multi-tenanted, serving millions of clients with shared compute
  • Operating systems often host multiple tenants on a single machine
  • Networks can supply connectivity to multiple teams or organizations via a single infrastructure.

All these scenarios have these necessary requirements in common:

  1. Each tenant’s data must remain private and accessible to only that authorized tenant, and
  2. Each tenant needs access to reliable, predictable, or contracted resources – such as bandwidth, compute, storage, security services, expertise, etc.

Multi-tenancy can help organizations to scale critical security services in a cost-efficient manner. A capable security architecture/service requires a significant capability investment and the expertise to operate it. By enabling this investment to be shared, it enables services to be made available to organizations that might otherwise not have been able to afford them.

A good example of where Multi-Tenancy can be extremely useful is the Security Operations Center (SoC). Typically, only large, well-funded organisations have the resources to build their own dedicated SoC. Multi-tenancy can enable multiple organizations to share a SoC, each benefiting from a strengthened security posture without carrying the full burden of the costs and effort involved.

This is the model underpinning outsourced MSSP services, for example. But it can also be an ideal model for larger organizations with multiple divisions that each need to maintain separation from each other. Or where multiple individual companies are owned by a common parent. It can also be a useful way to safely isolate a newly acquired company until its systems can be safely migrated or transferred over to the new owner’s infrastructure.

We see lots of areas where organizations are benefiting from this ability to  share infrastructure and services. So we are very pleased to announce that with the new OSm 7.1 software release, EndaceProbe Analytics Platform now also supports Multi-Tenancy for network recording.

This is especially useful where multiple tenants share the same network. A single EndaceProbe, or a fabric of EndaceProbes, can now be securely shared across multiple different organisations or tenants, while keeping the data for each tenant secure and private. EndaceProbes continuously record all network data on the shared network, but only provide each tenant with access to their own data.

In this case the tenancies are defined by VLANs, where each tenant has a VLAN, or set of VLANs, that carries only their traffic. When a user needs to investigate a security threat in their tenancy, they simply log into InvestigationManager to search, inspect, and analyse only the traffic that belongs to that tenancy. It’s as if each tenant has its own, wholly separate, EndaceFabric, dedicated just to its own tenancy.

This new capability is important for large organisations that service multiple departments, agencies, or divisions. Service providers, MSPPs, and MDRs which service multiple clients will also benefit from Multi-Tenancy to give each of its clients ready access to its own recorded network traffic for fast, secure, and private, security incident response.

We are very excited that this new Multi-Tenancy feature can help make Network Recording accessible for many more organizations, helping them to resolve incidents faster and with greater confidence.

For more information on this great new feature, or to arrange a demonstration to show how Endace could help you, contact us.

Watch Endace on Cisco ThreatWise TV from RSA 2019

Original Entry by : Endace

It was a privilege to attend this year’s RSA cybersecurity event in San Francisco, and one of our top highlights was certainly the opportunity to speak to Cisco’s ThreatWise TV host Jason Wright. Watch the video on Cisco’s ThreatWise TV (or below) as Jason interviews our very own Michael Morris to learn more about how Cisco and Endace integrate to accelerate and improve cyber incident investigations.

In this short 4 minute video, Michael demonstrates how Cisco Firepower and Stealthwatch can be used together to investigate intrusion events, using Cisco dashboards and EndaceVision to drill down into events by priority and classification to show where threats come from, who has been affected and whether any lateral movement occurred, as well as conversation history and traffic profiles. Michael also explains how Cisco and Endace work together to ‘find a needle in a haystack’ across petabytes of network traffic.

A big thanks to Cisco and to Jason for giving us this spotlight opportunity. If you have any questions about how Cisco and Endace integrations can accelerate and improve cyber incident investigation, visit our Cisco partner page.
