A Cisco blog post by Kajal Sharma promotes the Cisco Secure Firewall 200 Series as a branch-office firewall for AI-enabled applications, cloud services and hybrid work. It is vendor product marketing and reports no incident, vulnerability or threat activity. The post argues that branches are attractive targets because they have limited on…
Cisco PSIRT announced that on October 21, 2026 it will publish security advisories and fixed software releases for several products. The products are Expressway Series, IOS XR Software for ASR 9000 Series Routers, Secure Client, Snort and Unified Communications products. The Expressway, Snort and Unified Communications releases are descri…
The Cisco Splunk 2026 State of Observability report, published on October 20, finds that organizations are deploying AI agents faster than they can build monitoring procedures and security controls. This leaves them exposed to security threats, hallucinations and related problems. Of the 2050 ITOps and engineering respondents, 38% said th…
Cisco described how its team ran the live Security Operations Center at Splunk .conf26 in Denver, protecting more than 5,145 attendees from 70 countries. The SOC used a multi-stage agentic pipeline: live telemetry feeds Splunk Enterprise Security, autonomous triage agents accelerate Tier 1 analysis, Cisco Cloud Control enforces confidence…
Cisco describes how it is adapting its Cisco Secure Development Lifecycle (CSDL), built on more than 400 software security requirements, to AI-assisted and agentic software engineering. The security bar is unchanged, but requirements become atomic, machine-readable and contextual so that engineers and AI agents can act on them directly. C…
A Cisco security blog post by Jonathan Felten argues that cryptographic failures rarely come from broken algorithms. They come from the gap between a fix being available and a fix being deployed, which he calls the "last mile of trust". He says AI-driven vulnerability discovery is widening this gap because discovery scales with compute wh…
At Splunk .conf26, Cisco, Splunk and Endace ran a live Agentic Security Operations Center (SOC) built around the Splunk Enterprise Security (ES) AI Triage Agent. The agent prepared findings, with a suggested disposition, rationale and next steps, and human analysts validated the evidence and made the decisions. No threat activity or incid…
During the Splunk .conf conference, Cisco's Encrypted Visibility Engine (EVE) in Firewall Threat Defense (FTD) produced a previously unseen detection of Flawed AMMYY, a RAT built from leaked AMMYY source code, alongside the usual detections of Upatre, Xpiro and Quasar. Detections arrived in HTTP/HTTPS pairs with identical timestamps from …
GreyNoise announced Project Swarm, a research initiative that opens its deception platform, the Global Observation Grid (5,000+ sensors in 80 countries, 500M+ sessions per day), to outside contributors. The stated aim is better visibility into attacks on network edge devices (firewalls, VPN gateways, routers, load balancers). These device…
Cisco and Splunk ran a live Agentic SOC at Splunk .conf26, combining Cisco Cloud Control, Splunk Enterprise Security (ES), Cisco Talos intelligence and Endace continuous packet capture, with Jamf engineers also on the team. The article is largely a product and event retrospective. Its one security incident was a fake-Corepack npm credenti…
Cisco's Agentic SOC team at Splunk .conf26 showed how retrospective packet replay can check for past zero-day exploitation. They used full line-rate packet capture from Endace, intrusion detection on Cisco Secure Firewall Threat Defense (FTD), and rule updates from Cisco Talos. The scenario was Talos releasing new rules for CVE-2026-82329…
A Cisco blog post by Renato Morais compares past landmark threats with the emerging risk from autonomous AI agents, then presents Cisco's agentic security reference architecture. It recounts the ILOVEYOU worm (2000), a social-engineering email worm, and WannaCry (2017), a ransomware worm using EternalBlue against unpatched Windows systems…
GreyNoise reports that on 14 May 2026 its Global Observation Grid recorded 119,842 malicious, non-spoofable IPs targeting edge infrastructure. Compared against eleven widely used OSINT and commercial feeds, average coverage was 2.0%, and no single feed exceeded 5%. Even the largest list (Avastel, about 500,000 IPs) caught under 2%, and ve…
