Introduction: A New Era of Security Operations Has Arrived
Cybersecurity is no longer just about reacting to alerts—it is about understanding the complete story behind every digital event. As cyber threats become more sophisticated, Security Operations Centers (SOCs) must evolve beyond traditional monitoring and embrace intelligent automation without sacrificing human judgment.
During Cisco Live Americas 2026, this transformation became a reality. The Security Operations Center showcased how Agentic AI, cloud-native investigation platforms, and full packet capture technologies could dramatically improve the efficiency of new analysts while allowing experienced investigators to focus on deeper incident analysis. Rather than replacing security professionals, artificial intelligence became an intelligent teammate capable of accelerating investigations, validating hypotheses, and uncovering hidden attack paths that would otherwise remain unnoticed.
This event demonstrated that the future of cybersecurity belongs to organizations capable of combining machine-speed automation with experienced human decision-making.
A Tier Two
Serving as an experienced Tier Two Analyst inside the Cisco Live Americas 2026 Security Operations Center meant much more than reviewing security alerts. The role involved validating investigations performed by newly trained SOC analysts, many of whom had less than three days of experience.
These new analysts relied heavily on Agentic AI, which assisted them by collecting evidence, correlating security events, identifying suspicious behaviors, and generating detailed summaries. Their responsibility resembled emergency first responders arriving at the scene of an accident—they gathered facts, documented evidence, and developed an initial understanding of what had occurred.
However, while AI could rapidly assemble a highly accurate picture of an incident, experienced investigators were still essential for determining the actual root cause and confirming whether suspicious activity represented a real compromise.
Transforming Beginners into Skilled Investigators
One of the most remarkable achievements during Cisco Live was how quickly inexperienced analysts became productive investigators.
With AI-assisted workflows, Cloud Control capabilities, Splunk Security analytics, and Endace packet capture technology, a team of only eight new analysts successfully managed an enormous security workload.
Their responsibilities included analyzing:
Nearly 199 terabytes of captured security data.
More than 62,000 unique connected devices.
A total of 187 confirmed security incidents requiring investigation.
Without AI-powered assistance, handling this scale of operations would have required a significantly larger team with years of collective experience.
Instead, automation dramatically reduced the learning curve while maintaining investigation quality.
Managing the Incident Queue Efficiently
Like emergency dispatch centers, the SOC organized incoming alerts into structured incident queues.
Each analyst could view:
Incident severity levels.
Creation timestamps.
Latest activity.
Current assignment status.
Investigation progress.
This structured workflow ensured that high-priority threats received immediate attention while allowing analysts to distribute workloads efficiently.
Instead of overwhelming new analysts with thousands of isolated alerts, AI grouped related events into meaningful investigations that were easier to understand.
AI Delivers Instant Attack Verification
Every incident automatically included an AI-generated investigation summary.
Rather than forcing analysts to manually examine hundreds of log entries, the AI stitched together evidence collected from multiple security products into one comprehensive report.
The generated summary included:
Relevant log correlation.
Attack timeline.
Possible attacker techniques.
MITRE ATT&CK mapping.
Confidence scores.
Estimated likelihood of a true compromise.
In many cases, AI successfully determined that an alert represented a genuine attack while simultaneously acknowledging uncertainty regarding the attack’s original cause.
For example, a detection might receive:
True Positive: High likelihood that malicious activity occurred.
Low Confidence: Insufficient evidence explaining why the activity happened.
This distinction prevented analysts from prematurely closing investigations and encouraged deeper analysis.
Cloud Control Expanded Every Investigation
Cloud Control enabled analysts to validate AI-generated hypotheses rather than accepting automated conclusions blindly.
Instead of asking:
Did something suspicious happen?
Analysts could investigate:
Why it happened.
How it started.
Which systems communicated.
Whether misconfigurations existed.
Whether user behavior contributed.
This capability transformed investigations from simple alert validation into comprehensive incident response exercises.
Pivoting into Endace for Full Packet Visibility
Whenever analysts required deeper insight, they pivoted directly into Endace.
Endace continuously recorded full packet capture across the Cisco Live infrastructure.
Unlike traditional log analysis, full packet capture preserved every network conversation exactly as it occurred.
This allowed investigators to reconstruct events in extraordinary detail.
By simply selecting an IP address from an incident, analysts automatically opened Endace with:
Ten minutes of historical traffic.
Directionless packet filtering.
Related application traffic.
Communication history.
Instead of searching manually, investigators immediately viewed the entire network conversation surrounding an incident.
Finding the Story Behind Every Alert
Experienced investigators emphasized one important lesson:
Every alert has a story.
Malicious URLs rarely appear randomly.
Unexpected applications usually have a cause.
Unencrypted communications often reveal forgotten configurations or insecure software.
Instead of stopping after AI validated suspicious traffic, analysts searched for the underlying narrative.
Questions included:
Did someone accidentally expose credentials?
Was malware communicating externally?
Was outdated software still running?
Was sensitive information transmitted without encryption?
Was an attacker exploiting forgotten services?
Understanding these questions helped analysts educate users rather than simply resolving alerts.
Visualizing Communications Through Chords of Conversation
One of
Rather than displaying raw packet lists, investigators viewed interactive communication diagrams connecting every device involved during the investigation window.
Each connection represented ongoing conversations between systems.
Brighter and thicker lines indicated larger data transfers.
This visualization immediately revealed:
Unexpected external communications.
High-volume transfers.
Hidden network relationships.
Secondary endpoints involved in the incident.
Analysts could isolate only the communication relevant to the investigation and eliminate unnecessary background traffic.
Using Wireshark for Deep Packet Analysis
Once investigators identified suspicious communication, they opened the captured traffic directly inside Wireshark.
Here, every packet became visible.
Investigators searched for:
Credentials transmitted in clear text.
Malware command traffic.
Misconfigured applications.
Authentication failures.
Suspicious protocols.
Data leakage.
Encryption mistakes.
Even relatively small transfers—such as an 11 MB communication—could contain valuable forensic evidence explaining the entire incident.
Rather than assuming AI had found everything, analysts used packet analysis to confirm the complete attack chain.
Education Became Part of Incident Response
An important lesson from Cisco Live was that incident response should not end with threat containment.
Whenever analysts discovered insecure user behavior, they educated conference attendees.
Examples included:
Encouraging encrypted communications.
Removing vulnerable software.
Correcting insecure configurations.
Eliminating exposed passwords.
Explaining safe networking practices.
This educational approach reduced future incidents while improving the overall security posture of event participants.
Deep Analysis
Command 1: AI Should Accelerate Investigation—Not Replace Analysts
Cisco Live demonstrated that Agentic AI performs exceptionally well when handling repetitive investigative tasks such as correlation, enrichment, prioritization, and evidence gathering. However, final decisions still require experienced human analysts capable of understanding business context, attacker intent, and subtle anomalies that automation may overlook.
Command 2: Validate Every AI Conclusion
Even when AI labels an incident as a True Positive, investigators should independently verify supporting evidence. Blind trust in automated systems introduces risk, particularly when confidence levels remain low or endpoint visibility is incomplete.
Command 3: Full Packet Capture Remains One of the Most Valuable Forensic Assets
Logs reveal that an event occurred. Packet capture reveals exactly how it occurred. Organizations investing in full packet capture gain an invaluable resource for incident reconstruction, malware analysis, and compliance investigations.
Command 4: Visualization Simplifies Complex Threat Hunting
Interactive communication graphs dramatically reduce investigation time by helping analysts understand relationships between devices. Visual analytics often expose attacker infrastructure much faster than traditional log searches.
Command 5: Training Plus AI Outperforms Either Alone
The Cisco Live experience proves that AI does not eliminate the need for skilled professionals. Instead, it dramatically shortens the learning curve, allowing junior analysts to contribute meaningfully within days instead of months.
Command 6: Security Awareness Is a Defensive Technology
Many incidents originated from user mistakes rather than sophisticated attacks. Every investigation should end with education that reduces the likelihood of future compromises.
Command 7: Human Curiosity Is Still the Ultimate Detection Engine
The best investigators continuously ask “why” rather than accepting initial evidence. AI identifies suspicious behavior, but human curiosity uncovers the complete story behind every alert.
What Undercode Say:
The Cisco Live Americas 2026 SOC represents one of the strongest real-world demonstrations of practical AI integration within cybersecurity operations. Rather than replacing analysts, Agentic AI functioned as an experienced assistant capable of reducing investigative fatigue and dramatically accelerating response times.
What makes this deployment particularly impressive is its balanced architecture. AI generated summaries, correlated events, prioritized alerts, and suggested likely attack techniques, yet experienced analysts remained responsible for verification and strategic decision-making. This human-in-the-loop model addresses one of the biggest concerns surrounding AI adoption: overreliance on automated conclusions.
Another significant takeaway is the emphasis on evidence quality. Modern SOCs often struggle with alert overload, but Cisco’s workflow shows that intelligently stitched investigations provide far greater operational value than isolated notifications. Analysts spend less time collecting data and more time understanding it.
The integration with Endace further strengthens this ecosystem. Full packet capture is frequently underestimated due to storage costs and operational complexity, but Cisco Live demonstrated that preserving complete network conversations provides unmatched forensic visibility. When paired with AI-generated context, packet capture becomes far more accessible, even for less experienced investigators.
The success of newly hired analysts also highlights the changing nature of cybersecurity careers. Future SOC professionals may no longer require years of repetitive log analysis before contributing to advanced investigations. Intelligent assistants can shorten onboarding while allowing newcomers to learn through guided investigations.
However, organizations should resist viewing AI as a complete replacement for experienced analysts. AI systems remain dependent on available telemetry, data quality, and training models. Missing endpoint visibility or incomplete logs can still produce uncertainty, making human validation indispensable.
Another noteworthy aspect is
The operational scale managed during Cisco Live also demonstrates the growing importance of automation. Handling hundreds of terabytes of data and tens of thousands of devices would be nearly impossible using traditional manual workflows alone.
Looking ahead, similar AI-assisted SOC architectures will likely become standard across enterprise environments. Vendors are increasingly integrating large language models, behavioral analytics, and autonomous investigation capabilities into security platforms.
The future SOC will likely consist of analysts supervising intelligent systems rather than manually processing every alert. Human expertise will shift toward strategic investigations, threat hunting, adversary emulation, and incident leadership while AI performs repetitive analytical tasks at machine speed.
Ultimately, Cisco Live 2026 provides a compelling blueprint for the next generation of cybersecurity operations—one where artificial intelligence enhances human expertise instead of replacing it.
