Tech Stack 2026

“Well integrated with the CDN, fairly simple to implement in blocking mode without risk of false positives.”

Tech Stack 2026
8/10

“It works well, just lacks a bit of responsiveness at times.”

Tech Stack 2026
9/10

“Very practical and easy to implement when you are already a Fastly customer. Can be activated in a few minutes without much risk of false positives.”

Tech Stack 2024
10/10

“Meets the needs. Not enough hindsight yet, implementation in progress.”

Tech Stack 2024
8/10

“Very simple to implement, relatively effective "out of the box" without much configuration by technical security experts. It is very effective as a WAF. On the other hand, it doesn't replace a DataDome for anti-bot, for example.”

Adoption rates and satisfaction scores come from the Tech Stack study, an independent study run with the Sciences Po School of Journalism. Adoption is the share of questionnaire respondents citing the tool; satisfaction is the average score out of 10 given by its users. No score is published below 3 responses. Vendors cannot influence these results: they can only complete the presentation of their tool (description, case study, website, logo).
