The service has been very fast in responding to any problem we have mentioned during our conversation with them (about half way through their website). Good understanding between customer support team & project management teams about how things should be handled or what could go wrong if not managed properly at each stage! Also they help us resolve issues as soon after raising it without making unnecessary delays for end-users who are unable/unwilling enough handle such changes themselves! Nothing significant so far but would like some more experience working together before commenting further ;) I feel that this partnership made all my previous experiences seamless while starting off from scratch by myself when dealing remotely via Skype :) It's nice knowing there're people out here willing do work just because you want something done well rather than charging extra money which makes one think twice :D And great communication skills too!! We used detacks' products within different projects related mainly towards web application pentesting using OWASP ZAP toolkit / metasploit module etc., As always We have used Detack for a year now. They have done several penetration tests for us and always deliver on time. The support is very good and they are always willing to help. I can't think of anything bad to say about them. I would recommend them. We use Detack for penetration testing and vulnerability assessment. They have helped us identify vulnerabilities in our system and have helped us fix them.
