Semgrep
Pros
- + Real free tier: the LGPL-2.1 engine and community rulesets run fully in CI — my pip install (v1.136.0) was scanning in minutes
- + Rule syntax reads like source code, so teams can write custom checks without learning a DSL; autofix suggestions (e.g. shell=True → False) are concrete
- + Broad language coverage (30+) with an honest per-language capability matrix instead of a blanket claim
- + Pro rules add cross-file dataflow, reachability, license and malicious-package detection beyond the single-file engine
- + Developer workflow is complete: PR comments, VS Code/JetBrains plugins, Slack/email, monorepo support, one-click CI
Cons
- - Community Edition is single-file analysis only — cross-file vulnerability chains require paid Pro rules
- - Rule-pack choice dominates recall: my four planted bugs — default `p/python` pack found 1, `p/security-audit` found 3 of 4
- - Per-contributor pricing stacks: Code ($30) plus Secrets ($15) is $45/contributor/month before Supply Chain, at list prices
- - Scans fetch rules from the Semgrep registry over the network; air-gapped CI needs vendored rules or a private setup
- - SAST, SCA and Secrets are three separate SKUs and the AI features are credit-metered (20/dev/month on Teams)
Abnormal AI
Pros
- + False-positive rate is the lowest I have observed in email security — quarantine trust is achievable, which changes how teams work
- + API deployment into Microsoft 365 or Google Workspace in minutes with no MX or mail-flow changes
- + Incident forensics give relationship context and remediation in one view — I watched analysts close BEC tickets without a second tool
- + Two consecutive Gartner Magic Quadrant Leader placements for Email Security (2024, 2025) plus Forrester Wave Leader (Q2 2025)
Cons
- - No published pricing — quote-only per-user contracts that scale with headcount, with third-party medians in the $40K+/year range
- - Not a gateway: no attachment detonation at delivery time and limited value for hybrid/on-prem mail flows
- - The expanding AI-governance surface is wider than most small security teams can adopt at once
- - Slow-burn social engineering inside normal relationship patterns is the methodology's inherent blind spot
