Where the difference shows up in practice
Lovable-BOLA-class bug introduced in PR
XBOW: XBOW finds in next engagement (days-weeks later); generalist offensive may not target Supabase-specific patterns.
Securie: Securie's Supabase RLS specialist catches before merge in 30-90s.
.claude/settings.local.json committed
XBOW: XBOW's offensive scope doesn't typically include credential-leak detection.
Securie: Securie's secret_scanner specialist live_validates and blocks at PR time.
MCP RCE-class vulnerability
XBOW: XBOW would need to reach the MCP server in scope; default offensive scope doesn't include it.
Securie: Securie's mcp-guard crate refuses dispatch by construction.
Auditor asks 'how do you know it's fixed?'
XBOW: XBOW report alone is not auditor-evidence.
Securie: DSSE-signed in-toto v1 attestation; auditor verifies with cosign verify-blob.
The deeper tradeoff
XBOW's bet is autonomous offensive at scale — find more bugs, faster, cheaper than human red-teamers. The bet works for the segment that has engineering capacity to act on findings + the budget to engage.
Securie's bet is closed-loop coverage — find + fix + attest + monitor in one platform. Different buyer profile, different price point.
The specialist-fleet axis is the second difference. XBOW's offensive is generalist; Securie's specialists target the AI-built-app bug classes Apr 2026 incidents demonstrated (Lovable BOLA, .claude/ leaks, MCP RCE).
Most honest answer: try Securie first; layer XBOW for offensive enterprise scale if your operating model fits.

Migration playbook
Step 1: Run Securie + XBOW parallel 4 weeks
What: Both tools, same scope.
Why: Compare coverage + cost + workflow.
Gotchas: XBOW engagements are batch-shaped; Securie is continuous.
Step 2: Decide based on the closed-loop
What: Does your team act on XBOW findings without follow-on tooling?
Why: If yes, keep XBOW. If no, the gap is the closed loop = Securie.
Gotchas: Don't underestimate the Eng-velocity tax of unfilled findings.
When to pick XBOW
Enterprise with dedicated red-team budget + engineering capacity to act on autonomous-offensive findings.
When to pick Securie
Closed-loop coverage with auto-fix + auditor evidence; AI-built-app specialist depth; pricing reachable for indie + startup.
Bottom line
XBOW for enterprises with dedicated red-team budget. Securie for everyone else (closed-loop + auditor evidence + AI-built-app specialist depth).
FAQ
Can I run both?
Yes — XBOW for autonomous offensive, Securie for closed-loop defense + AI-built-app coverage. Most teams sunset XBOW once Securie's offensive swarm SKU covers the same scope.
Is XBOW just a feature?
No — XBOW is a legitimate product. The buying signal is whether you need autonomous offensive without the closed-loop. Most teams need the loop.
Pricing for sub-Series A?
XBOW unreachable. Securie Indie ($12) + Solo Founder ($49) cover sub-Series A directly.
