Features, pricing, ratings, and pros and cons, compared head to head.
Core Security Outflank Security Tooling is a commercial red-team & adversary emulation tool by Core Security. RedELK is a free red-team & adversary emulation tool. Compare features, ratings, integrations, and community reviews side by side to find the best red-team & adversary emulation fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
Mid-market and enterprise red teams will find Outflank Security Tooling essential for testing EDR bypass at scale; its steganography-based payload concealment and unpublished EDR evasion techniques let operators validate detection gaps that commodity toolkits can't expose. The continuous operator documentation and Cobalt Strike integration mean your team stays current as vendors patch, and on-premises deployment keeps artifacts off shared infrastructure. Skip this if your mandate is offensive security without a specific EDR validation requirement; Outflank assumes you're already comfortable with advanced post-exploitation and are hunting for the gaps most red teams never find. Red team operators running multi-day penetration tests need RedELK to watch what the blue team is actually detecting in real time, so they can adapt their techniques before getting caught. The tool ingests and correlates Cobalt Strike, Metasploit, and custom C2 logs against common detection signatures, letting operators spot IOCs and adjust tactics mid-engagement. Skip this if your red team operates at a pace where detection feedback loops don't matter, or if you lack the infrastructure to run a parallel ELK stack alongside your engagement infrastructure.
