The alternatives in detail
In order of how closely each one matches RunSybil.
Superagent
4.0Free
vs RunSybil−0.1Free plan
An AI security service that finds vulnerabilities in repos, web apps and agents, then fixes them.
- Finds and fixes vulnerabilities rather than only reporting them
- Covers repositories, web applications and AI agents
- Continuous scanning rather than periodic penetration testing
Delivering fixes removes the step where security work usually stalls
Automated fixes still require review before merging
ZeroThreat.ai
4.0$100/mo
vs RunSybil−0.1Free plan
AI-powered DAST scanner checking web apps and APIs against 40,000+ vulnerabilities.
- DAST scanning across web applications and REST APIs
- Library of 40,000+ vulnerability checks
- Vendor-stated 98.9% detection accuracy with low false positives
Free tier lets you scan before committing to a plan
Per-target pricing grows costly across a large application estate
Enkrypt AI
4.1Not listed
vs RunSybilSame
Security and safety testing for AI systems, covering threat detection and ongoing monitoring.
- Security and safety testing specific to AI systems
- Detection of prompt injection, jailbreaks and harmful output
- Vulnerability remediation rather than reporting alone
Addresses failure modes conventional application security misses
Only relevant to organisations actually deploying AI systems
Mobb
4.0$20/mo
vs RunSybil−0.1Free plan
Fixes security vulnerabilities in code rather than only reporting them.
- Automatic remediation of scanner findings
- Fixes delivered into the developer workflow
- Works from existing security tooling
Produces fixes rather than adding to a findings backlog
Generated fixes need review before merging
Nullify AI
4.0$67/mo
vs RunSybil−0.1
Autonomous AI agent that finds, prioritizes, and fixes code vulnerabilities.
- Autonomous vulnerability detection, triage, and merge-ready autofix pull requests
- Direct GitHub and Slack integration for repository assessment
- Unlimited repositories and users on the Pro tier rather than seat-based limits
Moves past detection-only scanning by opening autofix pull requests directly
No free tier, so evaluating the product means committing to the $800/year Pro plan
Simbian
4.0Not listed
vs RunSybil−0.1
AI security agents covering SOC triage, threat hunting and automated pentesting.
- AI SOC agent for alert triage and investigation
- Threat hunting triggered by SOC findings
- Automated pentest agent that feeds detection gaps back
Agent handoff targets the correlation work analysts do manually
Autonomous security actions need tightly scoped permissions
Seal Security
4.1Not listed
vs RunSybilSame
Remediation agent that ships production-ready fixes for open source vulnerabilities.
- Production-ready fixes for open source vulnerabilities
- Backported patches that avoid breaking version upgrades
- Human vetting of fixes before delivery
Backports avoid forcing breaking dependency upgrades
Ecosystem coverage should be confirmed for less common languages
Traceable
4.1Not listed
vs RunSybilSame
Discovers every API you have, tests them in the pipeline, and blocks attacks at runtime.
- Continuous API discovery and risk assessment
- Security testing inside the development lifecycle
- Runtime protection against live attacks
Finds the shadow APIs that inventories miss
No published pricing
