About Bryan Holleman

Building a strong, committed presence in cybersecurity services within the Channel space as a part of a thriving MSSP (Solutions Granted) and via acquisition a part of SonicWall has now led to an incredible opportunity with Horizon3.ai. From the amazing experiences collaborating with MSPs, MSSPs, Vendors, and teammates locked in to educating, supporting, promoting, and finding the right tools combined with people and processes to establish a strong defensive posture, I am now on the offensive side. What we are doing at Horizon3.ai with a team of \"learn-it-alls\" from top to bottom is inspiring and necessary to address challenges MSPs/MSSPs and small businesses to large enterprise face: How do we prove the value of tools deployed?How do we know if the defensive security tools, SOC, SIEM are performing as advertised?How can I ensure the vulnerabilities detected are actually exploitable in our environment? How do account for the other 364 days after we\'ve had a manual penetration test completed in our environment to ensure changes to our environment after the pen test hasn\'t left us exploitable? How do I report to all stakeholders when they ask if our environment is continuously protected and free of exploitable vulnerabilities?
