Pen tests. Active attacks. Deal timelines. We fix what's broken.
Multiple PE-backed companies needed security work done fast — pen test remediation, vulnerability assessments, credential hardening, DDoS mitigation, and a zero-downtime cloud migration. All under deal or audit pressure.
Overview
Impact, measured in results
Pen test remediation, vuln assessment, credential hardening, DDoS response, cloud migration
AWS to Azure migration executed with zero service interruption
Every remediation cleared compliance within the deal timeline
Multiple private equity-backed companies across healthcare, benefits administration, and proptech. Each facing security and compliance requirements tied to due diligence, audits, or active threats — on platforms serving millions of members and processing sensitive financial and health data.
Why AppStream
We had pen test findings that needed to be resolved before the deal could close. AppStream got it done on our timeline, not theirs.
Operating Partner
PE Firm
Scope it tight. Fix what matters. Document everything.
Each engagement started with the specific risk event: a pen test report, an upcoming diligence review, an active attack, a migration requirement. We scoped remediation to the timeline and the threat, not a generic security assessment.
For the pen test and vulnerability work, we prioritized by severity and deal impact, remediated the findings, and delivered audit-ready documentation that satisfied compliance reviewers. For the credential issues, we eliminated plain text passwords, implemented secure hashing, and rolled out MFA across affected platforms.
The DDoS response was immediate — identify the attack vector, mitigate, restore service, protect against recurrence. The AWS-to-Azure migration was planned and executed with zero downtime, improving security posture while cutting infrastructure costs. Every engagement delivered the technical fix and the paperwork to prove it.

Real-world examples of solving complex problems and scaling challenges.
Enterprise scheduling platform on top of legacy EMR
A health system with 100+ clinics was stuck on a scheduling module that couldn't keep up. We built a new scheduling engine on top of their EMR instead of replacing it.

A DME startup was writing off revenue because nobody could predict which placements would get reimbursed. We built an AI engine that checks every case against Medicare and Medicaid policy before anything goes out the door.

The nation's largest flat fee brokerage had a sell-side business but no way for buyers to search, discover, or transact. We built the marketplace and a proof-of-concept for AI-powered property search that understands context, not just filters.
