Beyond RASP Security

The bad news: 100 percent of web applications are vulnerable. It’s not a typo: 100 percent of web applications contain at least one vulnerability — on average, apps have 11 potential weak points.

Should Security Teams Use CSP Nonces to Better Comply with PCI?

This week, tCell sponsored BSidesSF [https://bsidessf.org/].

Stateful WAF AKA the Bronze Age

The first post in this series kicked off our history series on the development of web application firewalls [/stateless-web-application-firewall-aka-the-stone-age], with a discussion of what the earliest technology was capable of.

If the problem is that stone age WAFs have stateless rules, then the obvious
