AppSec Santa Weekly is a weekly newsletter that tracks new AppSec tools and the latest releases from 196+ existing ones. Each issue covers what shipped, what changed, and why it matters.
This week I counted six vendors launching “AI agent security” products at RSAC. I lost track of the press releases after the third one.
Meanwhile, a security scanner got weaponized against its own users — for the second time in three weeks. Busy week.
This Week at a Glance
25 releases across 5 active categories this week.
- SCA (12) — Renovate 5 releases, FOSSA 3 releases, Grype v0.110 APK matching fix, Snyk CLI adds agent red-teaming
- IaC Security (6) — Mondoo v13.1–13.2 adds SageMaker + F5 checks, Checkov TLS fix, Kubescape, Conftest, KubeArmor
- Mobile (3) — MobSF v4.4.6 patches SQLi in its own code, Ostorlab adds 2FA
- ASPM (3) — Harbor v2.15.0, NeuVector v5.5.0, DefectDojo 2.56.3
- SAST (1) — TruffleHog v3.94.0 Datadog verification fix
Quiet this week: DAST, IAST, RASP, AI Security, API Security
But the real action was at RSAC 2026 and in supply chain attacks. Read on.
New on the Radar
RSAC 2026 and the AI agent security rush — Every major vendor launched agent security at RSAC this week. Here’s who shipped what:
- Snyk
— Agent Security
: MCP server governance (Agent Scan), red-teaming via CLI
--profileflag, Snyk Studio for Claude Code/Cursor/Devin (300+ enterprise deployments) - CrowdStrike — Falcon AI Runtime Protection + Shadow AI Discovery; already detects 1,800+ AI apps on enterprise devices
- Microsoft — Zero Trust for AI (ZT4AI) framework + Agent 365 (GA May 1)
- SentinelOne — Prompt AI Agent Security with MCP governance
- Palo Alto — Prisma AIRS 3.0 + Cortex Cloud (merging Prisma Cloud and Cortex CDR)
- Geordie AI — Won the Innovation Sandbox; London-based agent security startup
My take: Six vendors, six “MCP governance” announcements. But here’s what I keep wondering: how many of these actually parse the MCP protocol and inspect tool calls versus just flagging “MCP detected” as a checkbox? The difference between real protocol-level inspection and a glorified inventory scan is the difference between a firewall and a clipboard. I’d love to see someone publish a benchmark. Until then, I’d weight Snyk’s approach (they actually ship a CLI you can test today) over announcements with a “GA Q3 2026” footnote.
Trivy GitHub Action compromised — again — Aqua Security’s trivy-action, a popular GitHub Action for container vulnerability scanning, was compromised for the second time in March 2026.
On March 19, attacker “TeamPCP” force-pushed 75 of 76 tags and published a malicious binary that exfiltrated AWS/GCP/Azure credentials, SSH keys, and Kubernetes tokens from CI/CD pipelines.
Root cause: incomplete credential rotation from the March 1 incident . Over 10,000 GitHub workflow files referenced the compromised action.
If your CI pipeline uses trivy-action@v1 or any mutable tag, check your pipeline logs and rotate any credentials that ran through affected workflows.
The Datadog State of DevSecOps report published the same week found that 71% of organizations never pin their GitHub Actions to commit hashes. That stat hits different now.
Semgrep Multimodal launches — Semgrep Multimodal is a new SAST approach that combines AI reasoning with deterministic rule-based analysis. Semgrep announced it on March 20 , claiming 8x more true positives with 50% fewer false positives versus base models alone.
The practical question is whether this holds outside of benchmarks — AI-assisted SAST has a history of impressive demos that don’t survive contact with real codebases. But multiple zero-days reportedly found at customer sites during the preview period suggests this might be different.
Also launched Custom Workflows (private beta) for autonomous code security.
Notable Updates
- MobSF v4.4.6 — Patched an SQL injection in its own SQLite DB viewer (changelog ). Yes, a security tool with its own SQLi. 20.7K stars, most-starred mobile security framework on GitHub.
- Harbor v2.15.0 — Tag deletion in GC, upstream registry connection limits, backend storage improvements (release notes ). At ~28K stars, one of the most-starred CNCF security projects.
- Grype v0.110.0 — Suppresses false GHSA matches on language packages in fixed APKs, cuts noise for Alpine-based container scanning. Now uses Syft for CPE decoding, pulling Anchore’s two tools closer together (release notes ).
- NeuVector v5.5.0 — Improved vulnerability reporting and Rancher SSO auth fix (changelog ). If you’re on SUSE Rancher, the SSO fix alone is worth the upgrade.
- Mondoo v13.1–13.2 — 9 new SageMaker checks, plus Ubiquiti UniFi and F5 BIG-IP policies. Mondoo is pushing beyond cloud-native into network infrastructure. v13.2 fixes an identity timeout bug (changelog ).
- TruffleHog v3.94.0 — Datadog detector verification fix and Filesystem source refactor (release notes ).
SCA
SCA leads for the second straight week with 12 releases across the SCA category .
Renovate shipped 5 releases (43.87.0 through 43.89.0), adding Packer support for mise and OpenTelemetry PHP monorepo presets. The volume is normal for Renovate — this tool ships more frequently than any other in our tracking.
FOSSA
shipped three releases: Elixir production dependency resolution with MIX_ENV=prod (v3.16.3), a macOS dynamic linking fix (v3.16.4), and a pnpm v9 devDependency classification fix (v3.16.5). The pnpm fix matters — incorrectly classifying dev dependencies as production creates false compliance violations.
Snyk
CLI v1.1303.2 introduces “Agent Red Teaming” with attack profiles (fast, security, safety) via the --profile flag.
This landed the same week Snyk launched their broader Agent Security platform at RSAC, with Agent Scan for MCP governance and Snyk Studio integration with Claude Code, Cursor, and Devin. Over 300 enterprises are reportedly using Snyk Studio.
IaC Security
Mondoo keeps shipping fast post-funding with two releases. v13.1.1 adds 9 SageMaker security checks, plus Ubiquiti UniFi and F5 BIG-IP security policies. v13.2.0 fixes an identity timeout bug and adds nftables support for policy scoping.
Checkov 3.2.510 updated three Terraform checks: modern TLS security policies for AWS CloudFront (CKV_AWS_206), current EKS Kubernetes versions (CKV_AWS_339), and Postgres 18 for GCP Cloud SQL (CKV_GCP_79). Small changes, but keeping checks aligned with current cloud service versions prevents false positives.
SAST
The only GitHub release was TruffleHog v3.94.0 (Datadog detector fix), but the bigger SAST news came from RSAC. Semgrep launched Multimodal (covered above).
Harness launched Secure AI Coding — a SAST capability that scans code at generation time, integrating with Cursor, Windsurf, and Claude Code. And ZeroPath, an AI-native engine replacing traditional SAST+SCA+Secrets stacks, was an RSAC Innovation Sandbox finalist.
Quiet This Week
No GitHub releases from DAST , IAST , RASP , AI Security , or API Security . Plenty of RSAC announcements though, just no shipping code.
Deals & Funding
Five deals worth tracking this week, including the largest acquisition of a venture-backed startup in history.
- Google completes $32B Wiz acquisition — Completed March 11, 2026. Wiz joins Google Cloud and will keep its brand across all cloud environments. This is the largest-ever acquisition of a venture-backed startup.
- Bold Security emerges from stealth with $40M — AI-native endpoint protection, led by Bessemer Venture Partners with Picture Capital and Red Dot Capital Partners.
- Fig Security launches with $38M — Founded by the former head of Google Cloud Security architecture and ex-Cymulate veterans; traces data flows through security stacks.
- BlueFlag Security raises $16.5M Series A — Developer identity security, treating each developer and their tools as an identity.
- Geordie AI wins RSAC Innovation Sandbox — Each of the 10 finalists received $5M in investment. Geordie’s agent security platform won against 9 other finalists including ZeroPath (AI-native SAST) and Token Security (machine identity).

Worth Reading
Datadog State of DevSecOps 2026 — The number that stuck with me: only 18% of “critical” vulnerabilities remain critical after applying runtime context. Also: 87% of orgs have at least one exploitable vuln, and 71% never pin GitHub Actions to commit SHAs.
Inside the Trivy-Action Supply Chain Compromise (Wiz) — Deep-dive on how incomplete credential rotation after the March 1 incident enabled the March 19 re-compromise. If you run any security tools in CI, read this.
Latio 2026 Application Security Market Report — James Berthoty’s annual analyst report. Recognizes Legit Security, Aikido, Contrast Security, Socket, and Apiiro. Key thesis: “runtime is the source of truth in AppSec.”
ProjectDiscovery State of AppSec 2026 — Makes the case that verification — not scanning — is the real constraint. Worth reading if you’re drowning in scan results with no proof of exploitability.
OWASP GenAI Security Frameworks — Pre-RSAC Update — New agentic red teaming taxonomy and GenAI data security risks guide. Useful if you’re building AI security policies and need a framework to start from.
Wrapping Up
That’s issue #2. 25 releases tracked, but the bigger story is RSAC 2026 and everyone racing to ship AI agent security. MCP governance went from niche to must-have in a single week.
I track 69 GitHub repos, 91 vendor blogs, and industry news sources every week. If a tool ships a release, changes its pricing, or gains traction — it’ll show up here.
If you found this useful, forward it to a colleague who’d benefit.
And if I missed something or got something wrong, just reply — I read every response.
See you next Tuesday.
