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)
SentinelOne AI
Pros
- + Rollback is real: in my controlled file-modification test the engine flagged, contained, and offered one-click restore of affected files
- + Agent deployment took minutes per machine in my Windows and macOS test environment, with no reboot required
- + Storyline turns multi-process incidents into one narrative view — my triage read dropped from roughly fifteen minutes to two
- + Six consecutive Gartner Magic Quadrant Leader placements (2026 report) and a long public MITRE ATT&CK evaluation record to scrutinise
Cons
- - Behavioral detection needs active tuning — my test environment produced false positives around installers and scripting tools in week one
- - Complete tier keeps data retention at 14 days; 90-day retention and managed threat hunting sit on higher tiers
- - Public pricing is USD-only and volume-tiered, so the $179.99 per endpoint figure is not what larger deployments pay
- - Identity threat detection and the agentic SOC analyst are gated above Complete (or sold as add-ons)
