Rockstar🎓
Top SchoolEric Gruber is a security research and operations leader with 13 years of experience building offensive and defensive capabilities at NetSPI, recently promoted to VP, Services Research. He has led the creation and scaling of an Attack Surface Management practice that turned continuous penetration testing into a 24/7 revenue-generating service and drove ARR past $1M. Technically hands-on, Eric has deep expertise in large-scale red team operations, cloud and application penetration testing, and custom tooling—his open-source PowerShell PEchecker demonstrates attention to low-level Windows binary hardening (ASLR, DEP, SafeSEH, Authenticode). He directs rapid detection pipelines that surface 0-day exploit activity to clients within hours, and enforces rigorous asset and vulnerability data quality across programs. With a Master’s in Computer Science from the University of Minnesota and a career that progressed from intern to VP within one organization, he combines institutional knowledge with a proven track record of innovation and operationalizing research.
