Top 3 Tech Challenges RASP/(ng)WAF Vendors Are Faced With

Here I’d like to share my experience and pain in building L7 data protection solutions which are frequently called WAF/ngWAFs or RASPs. I started to build it back in 2009 from a simple detection logic based on self-adopted heuristics for a CTF competition and then build an entire company on machi...
