"As part of our HMG Impact Level 3 security accreditation for hosting eSourcing services, we were happy to engage your services during May2009 (for our first accreditation) as well as February 2010 (for the annual renewal). In both occasions, you diligently carried out the Penetration Testing of the eSourcing system, both through internal access to our systems during on-site visits as well as externally over the internet afterwards.
As verified by our IT staff as well as HMG's Accreditors, you demonstrated in-depth knowledge of the security aspects of our project. The findings of your tests were useful as they identified potential security holes/risks and you also provided guidelines for the mitigation of these risks. Hence, we succeeded in attaining the required security level for hosting eSourcing services within our premises. In short, your services were valuable to us and we would be in favour of reengaging your services in the future."
Stefanos Christakis, Project Manager at European Dynamics
"Joseph was commissioned through Aristi to provide application penetration testing, Citrix Virtual Desktop breakout testing and DMZ level network testing. This was in relation to an IT solution being deployed to service a contract with the Department and Work & Pensions. The testing was part of assuring our delivery against the ISO27001 standard.
I was very happy with the quality of work undertaken - the work was done in a very timely manner against tight timescales. The report provided was very thorough and gave detailed analysis of any weaknesses identified and also how to resolve these to a satisfactory standard. The breadth and depth of testing was good and the DWP Security Team professionals commented on the excellent report that was provided.
Communication was excellent throughout the process and I would be happy to recommend his work to others."
