PHP2Shell Had Teeth, But The Real Story Is The Eclectic Mayhem

Erik Nost November 3, 2026
The week of October 20 was unusually chaotic, even without the PHP news. Not only did teams need to scramble to identify and understand the impact of emergency PHP vulnerabilities, but there were also critical vulnerabilities in Node.js, cryptographically weak keys issues by a certificate authority, exploited vulns in network security equipment, and potentially accidental […]

Break Out Of The Vulnerability Matrix At Forrester’s Security & Risk Forum 2026

Janet Worthington October 29, 2026
Security teams are hearing two competing stories. In one, AI completely rewrites the rules of vulnerability discovery, exploitation, and remediation. In the other, AI simply adds speed and scale to problems that security programs already understand. The reality lies somewhere in between. Discovery Is Accelerating Faster Than Decision-Making AI analyzes code, generates findings, and proposes […]

PHP2Shell Leak Sends Security Teams Scrambling

Sandy Carielli October 22, 2026
At 14:00 UTC on October 21, PHP released patches to two critical CVEs, both of which can lead to remote code execution. CVE-2026-109618 addresses an RCE through an out-of-memory error, and CVE-2026-109619 addresses an RCE through a stale global-state issue. The flaws were discovered by researchers at Wiz and Calif, the latter as part of […]

Merritt Maxim October 7, 2026
As a research director, I manage a team of analysts who cover a range of technologies outside my primary area of expertise (identity and access management).

Erik Nost September 30, 2026
Last week, we released The Forrester Wave™: Proactive Security Platforms, Q3 2026. This is the first evaluation of this market under this title, which has evolved from attack surface management and unified vulnerability management.

Harness Up For Our Black Hat 2026 Recap

Jess Burn August 10, 2026
Black Hat 2026 generated more questions than it answered. Are we headed for a vulnerability apocalypse (aka vulnpocalypse), or are we clearing a backlog of flaws that AI can now find with ease? Can organizations patch fast enough? What should buyers expect from vendors when software can reason? Will AI be our undoing or our […]

Total Recall: A Cautionary Fable Of Anthropic And The US Government

Jeff Pollard June 15, 2026
On Friday, June 12, the same model class covered by our previous blog post went dark. Anthropic suspended Fable 5 and Mythos 5 worldwide after the US Department of Commerce issued an export control directive, which led to requests from prominent cybersecurity pros to undo the action. The bypass that triggered the export controls, per […]

How Fable 5 And Mythos 5 Change AI Security, Data Retention, And Vendor Risk

Jeff Pollard June 10, 2026
Anthropic’s Fable 5 and Mythos 5 is the most 2026 product launch you’ll read this year. The same model can find nation-state zero days, design novel drug candidates, and play FireRed on a Gameboy Advance with nothing but screenshots. And for the gaming fans out there, yes, we got Fable 5 before Fable 4. These […]

OpenAI’s Daybreak Promises To Improve AppSec But Introduces A New Pricing Model: Five Buyer-Side Implications For CISOs

Jeff Pollard May 13, 2026
OpenAI recently announced Daybreak, its vision for making agentic application security faster and more capable. While promising, Daybreak will also make security more expensive per unit of work. In this model, customers will pay for tokens and multiagent workflows burn tokens. CISOs and CIOs should budget for application security (AppSec) line-item inflation, not deflation, with […]

Claude Code Security Causes A SaaS-pocalypse In Cybersecurity

Jeff Pollard February 23, 2026
We have seen this pattern before, even if the specifics look different. Think back to the day AWS introduced GuardDuty, when Microsoft folded Defender for Endpoint into its enterprise licensing commitments and launched Microsoft Sentinel, or when Google acquired Mandiant and eventually Wiz. Sure, the launch of fully autonomous AI agents that can ingest entire […]

The Success Of Your Proactive Security Strategy Depends On Your Answer To Six Questions

Erik Nost January 20, 2026
Proactive security has always been based on three principles: visibility, prioritization, and remediation. But in the age of AI, each principle will continue to experience challenges. In our latest research, The Future Of Proactive Security, we found that the future of proactive security hinges on how well teams answer six foundational questions across each principle: what, when, where, why, how, and who. Since AI accelerates […]

Proactive Security Platforms Will Cumulate Visibility, Prioritization, And Remediation

Erik Nost November 13, 2025
Last year, we released our inaugural Forrester Wave™ on attack surface management (ASM) solutions. The ASM Wave primarily focused on visibility — the first of the three principles of proactive security. ASM’s visibility is achieved through external asset discovery and ingestion of third-party information regarding asset attributes, and both features are becoming increasingly commoditized. Yet the ubiquity of […]
