-- TheCyberGrid.com has published the State of SaaS Security 2026, its quarterly industry report examining the externally visible security posture of 186 public SaaS companies, including Stripe, Twilio, Atlassian, and Zendesk.
The report analyzes publicly observable security signals across leading SaaS providers and highlights the continued gap between widespread adoption of encrypted web traffic and implementation of modern browser security protections.
According to the findings, 94 percent of the SaaS companies assessed have adopted modern Transport Layer Security (TLS), up from roughly 70 percent three years ago. However, only 39 percent have implemented a Content-Security-Policy (CSP), a browser security control designed to help mitigate cross-site scripting attacks. Just 12 percent of companies have deployed all six modern browser security headers recommended by the Open Web Application Security Project (OWASP).
Additional findings include:
- 70 percent of scanned companies are missing a Referrer-Policy header.
- 61 percent lack frame-embedding protection.
- One in eight companies still discloses its backend framework through an X-Powered-By response header.
"TLS became a solved problem the moment cloud infrastructure providers made it a default," said Shankar Nigam, Senior Security Engineer at CyberGrid. "Security headers still require someone in the application code to decide what value to set, and that decision keeps losing the internal prioritization fight. That is why we still see the same class of missing headers in every engagement we run."
Vertical breakdown
The report found that fintech and payments companies demonstrated the strongest overall external security posture, with 60 percent receiving grades of A or A-. Enterprise SaaS and vertical SaaS companies showed the widest variation in security performance, while consumer SaaS organizations recorded the highest rate of technology stack disclosure.
The complete report, including methodology, per-vertical analysis, and five practical recommendations for improving externally visible application security, is available on TheCyberGrid.com.
CyberGrid publishes the report on a quarterly schedule, with the next edition planned for October 2026.
Free public tool
Organizations can also generate a live security snapshot for their own domain using CyberGrid's public scanning tool. The assessment reviews HTTPS enforcement, TLS configuration, security header implementation, and stack disclosure before producing a letter-grade summary that can be compared with companies operating in the same industry. The tool is available without registration or payment.
