Got a sales call about Penetration Testing from this company called iSTORM Solutions (https://istormsolutions[.]co[.]uk/). Just thought I’d share in case anyone else gets a ring from them.

I just got a call out of the blue offering pen test services. Not sure if it’s legit or just another telemarketer trying to sell something I don’t need. Bit annoying really.
