Modern Cybersecurity Consulting
Cybersecurity consulting, built for the AI era
Fractional CISO leadership, AI and application security, cloud defense, and security engineering — for fast-moving SMB and growth-stage teams. Senior expertise, without enterprise overhead.
A certified Microsoft security partner
Our team holds the full Microsoft cybersecurity certification stack — from associate-level operations to expert-tier architecture. We're the consultancy Microsoft-shop SMBs hire when they need real expertise on Defender, Sentinel, Entra ID, Purview, and Azure security.
Security shouldn't be the thing slowing your team down
Most security firms were built for Fortune 500 buyers — six-figure retainers, six-month engagements, deliverables that gather dust. That model doesn't work for a 60-person SaaS company shipping AI features every week, or a healthcare startup three months from a SOC 2 audit.
You need senior security expertise that moves at your speed, integrates with your engineering team, and delivers work you can actually ship. That's what we built Defenssive to do.

Three reasons clients pick us over the alternatives
Senior engineers, not junior consultants
Every engagement is led by a security practitioner with 10+ years in the field. You're not paying enterprise rates for a graduate to fill out spreadsheets.
Global delivery, US-based leadership
Our delivery model means follow-the-sun coverage and cost structures that competitors can't match. We pass that math on to you.
Outcomes, not deliverables
You don't need another 80-page risk report. You need fixed vulnerabilities, passed audits, and a security posture that holds up. That's what we measure.
Cost reduction
Cut your security tool spend by up to 30% — without weakening posture
Most security budgets are bloated with overlapping tools, unused licenses, and shelfware nobody owns. Our security cost-reduction engagements consistently identify 20–40% in savings while strengthening — not weakening — your security posture.
We're vendor-neutral. We don't take kickbacks. The savings go to your bottom line.
