Honest, detailed comparisons with every major AI security tool. We highlight genuine trade-offs — not just where Rune wins, but when a competitor might be the better fit for your team.
Every vendor claims best-in-class detection. These comparisons cut through the marketing to evaluate what actually matters: detection methodology (ML classifier vs. multi-layer scanning vs. rule-based), integration depth (API proxy vs. framework-native middleware), latency characteristics (cloud round-trip vs. local scanning), and pricing transparency.
We include honest trade-offs — not just where Rune wins, but where competitors have genuine advantages. If a competitor is better for your specific use case, we'll say so. Our goal is to help you make the right decision, not just the decision that benefits us.
Two approaches to AI security — cloud-managed API vs framework-native runtime scanning
Conversation flow control vs runtime threat detection — different tools for different problems
Output validation vs runtime threat detection — complementary tools for different layers of safety
Self-hosted scanner library vs framework-native runtime security
Cloud API scanner vs framework-native runtime security with tool awareness
Enterprise AI firewall vs developer-first runtime security SDK
Open-source injection detector vs comprehensive agent security platform
Security platform service vs framework-native agent security SDK
Rune embeds directly into your agent framework as a middleware layer, scanning inputs, outputs, and tool calls inline — not through an external API call. This means lower latency (under 20ms for L1+L2), no data leaving your infrastructure for scanning, and the ability to scan tool parameters and inter-agent communication that API-based solutions can't see.
For startups, the key factors are speed of integration, free tier generosity, and framework support. Rune offers 10,000 events/month free, integrates in under 5 minutes, and supports all major frameworks. Lakera Guard has a generous free tier but requires more integration work. Open-source options like LLM Guard are free but require self-hosting.
We try to be as honest as possible. Each comparison includes a 'Why Choose [Competitor]' section with genuine advantages. We acknowledge when a competitor has better coverage in a specific area, longer track record, or features we don't offer yet. If you find inaccuracies, email hello@runesec.dev and we'll correct them.
The best comparison is hands-on. Add Rune to your agent in under 5 minutes and see how it works. Free tier includes 10,000 events per month.
