Top 10 Best RASP Tools in 2026 [Ranked & Scored]
Cyber Security News·Source published ·1 min read
What happened?
RASP’s idea block attacks from inside the running app won so convincingly that observability and edge platforms absorbed it, leaving a thinner standalone market that stale lists misrepresent. Rather than relying solely on pre-deployment scans from static application security testing (SAST) tools, modern engineering organizations deploy real-time runtime protection directly inside running workloads to intercept memory corruption, command injections, and zero-day execution paths.
Key details
- Waratek specializes in JVM virtual patching that neutralizes vulnerable behavior without source code changes or redeployment.
- Fastly's Signal Sciences operates as a Next-Gen WAF at the edge or container sidecar without invasive in-process instrumentation.
- Jscrambler focuses on client-side browser protection including JavaScript obfuscation, anti-tampering, and Magecart skimming defense for PCI compliance.
- Oligo Security brings modern ADR and runtime exploit detection using behavioral context and threat intelligence from researchers uncovering critical RCE vulnerabilities.
Affected
- Hdiv was acquired by Datadog in 2022 and powers its runtime protection.
- K2 Cyber carries a defunct-status flag and signals point to wind-down.
Fixes and mitigations
- Start runtime protection in monitor-only mode on one tier-one app, measure overhead and false-block rates, then graduate to blocking.
