They’ve possibly dug an even deeper hole now.

None of their ISO 27001 certificates, aside from the premium one-offs with the vCISO, are accredited by any reputable ISO accreditation body. I would even argue that IAS, who accredited Prescient Security (mentioned as a reputable body in the article), has a questionable reputation and certainly gives off a pay-to-play impression.

You can look up the names of their partners below. The one body I found that is on the register (Accorp) is accredited by UAF, a known cert-mill accreditation body, and I’m not even sure it’s the same Accorp that Delve has partnered with.

For reference, you want a ISO certificate issued by a body accredited by UKAS (UK gov. adjacent non-profit), ANAB (ANSI), or equivalent, all government-recognised. This is normally the first thing I check whenever someone claims ISO 27001 certification and it is a great heuristic to validate certification rigour.

Shockingly low levels of DD by everyone involved here.
