How Secure Are Your SaaS Applications? Pentesting for SaaS Providers

APIs expose backend logic and sensitive data directly; targeted API security testing uncovers broken authentication, excessive data exposure, and access control flaws that traditional pentests miss.

The 2023 OWASP API Security Top 10 keeps BOLA and Broken Authentication on top while adding SSRF, unrestricted resource consumption, and unsafe API consumption; industry pros react.

API security remains underprioritized as usage surges; the 2023 OWASP API Security Top 10 still leads with BOLA and broken authentication, and manual testing is needed where scanners fall short.

After a dull conference, the author concludes cloud pentesting is fundamentally the same as traditional testing: virtualized or shared, the underlying technology and security controls hardly change.

Since its formal recognition by the security community in 2007 on the OWASP Top Ten list, Cross Site Request Forgery (CSRF) has stepped out of the shadows and joined the ranks of vulnerability all-stars like Cross Site Scripting (XSS) and SQL injection.
