Analyst firm Gartner has advised in favour of the use of CAPTCHAs - but recommends using the least-annoying CAPTCHAs you can find.

The firm's opinion is contained in a post by senior director analyst Akif Khan, who noted that CAPTCHAs create friction for humans but remain an imperfect defence against bots.

He advised trying what he called "More evolved" versions out there, like those from Arkose Labs, GeeTest or PerimeterX. The analyst suggested that good CAPTCHAs should do more than ensure users provide a correct answer to a challenge, and also determine if answers are given too quickly - as would be the case for a professional paid per correct CAPTCHA test.

While Khan sees a role for CAPTCHAs, Cloudflare recently launched an anti-CAPTCHA manifesto.

The Cloudfare blog post suggested using Cryptographic Attestation of Personhood, essentially a hardware security key, as superior to CAPTCHAs.
