The value is clear, outcomes proven, and competitive rate unbeatable for what you get in return. Join us in a partnership to reduce risk!
Naming of 4D5A Security
4D5A Security is named after the hexadecimal representation of the two ASCII characters “MZ”, initials for Mark Zbikowski, who lead development of MS-DOS and the “magic number” seen in the header of any executable file on Windows. If you’re a threat hunter you’re looking for “MZ” in ASCII or “4D 5A” in ‘hex’ to confirm its an executable as part of content inspection when looking for hostile executables like that of malware.
The 4D5A logo is composed of two letters, M and Z, manipulated within an image program to create the image you see today, to the left of this description.

How does table top training work?
Tabletop exercises run by 4D5A Security demand outcomes that move the needle to reduce risk! Tired of ‘Ho Hum’ compliance driven exercises that are a waste of time? We partner with executives to identify perceived gaps, target areas of operations and risk, and involve every single stakeholder in simulations and injects for maximum output. We also use our own interactive assessments and metrics throughout, coupled with extensive monitoring and note taking, to capture gaps and recommendations to build out a prioritized risk roadmap following a tabletop exercise.
We also offer customized training. For example one client wanted to build out operations to augment MSSP services where they could start to handle their own malware samples and analyze some components of it for assurances and intel and also make sure the MSSP was doing a good job. We partnered to build out a safe and effective set of operations and then hosted a training workshop to prove it out in operations to onboard it for a successful launch into production.
