Montana Cybersecurity

Strategic Consulting for Big Sky Businesses

Montana businesses face a perfect storm of sophisticated cyber threats targeting resource-rich companies, limited local security talent, and the same federal compliance requirements as Silicon Valley—without the Silicon Valley budget.

  • Critical Access Hospitals managing ransomware risks on shoestring IT budgets
  • Energy companies defending infrastructure that nation-states actively target
  • Financial institutions serving vast geographic areas with small security teams
  • Growing tech companies competing globally while staying rooted locally

[Adversis] was incredibly helpful in conducting a security assessment for our new Saas product. Easy to work with, quick to do the assessment, and delivered a report that was actionable without a bunch of fluff.
Mike Julian
CEO, The Duckbill Group
Partnering with Adversis was one of my firm's best business decisions. The Adversis team did a fantastic job fortifying our cybersecurity defenses and guiding us through the complex world of cybersecurity with ease and clarity. The team was highly skilled, professional, and simply fun to work with. The process they used is impeccable. They took the time to learn about my business and equipped my team with the knowledge of how to keep our new security policies in practice. My firm is small, but they really made my team feel like we got the service and quality of a Fortune 500 company.
Drew Coco
Cofounder, Piedmont Capital Management
I've read through a few pentest reports and found yours better-written and containing a lot less fluff than average. It was also a lot more reasonable its severity assessment than ones I've read in the past: you highlighted legitimate concerns without blowing anything out of proportion. A+ would read again.




Software Engineer
Stealth Startup, San Francisco
We anticipated a standard penetration test—but what we received went far beyond that. Noah and the Adversis team became trusted advisors, bridging a critical knowledge gap in our organization. Their hands-on guidance through CIS v8 and GDPR alignment was instrumental. What would have taken us years to accomplish internally was achieved in months through their structured, transparent, and supportive approach.
