12# Pen tests. Active attacks. Deal timelines. We fix what's broken.
13 
14Multiple 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.

36## The work
37 
38Multiple 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.
39 
40What was getting in the way
41 
42- Pen test findings blocking a deal. The internal team didn't have the capacity or expertise to remediate before the compliance deadline.
43- A separate company needed a full vulnerability assessment before an acquirer's technical team started reviewing their systems.
44- Multiple TPA platforms storing passwords in plain text. HIPAA violations sitting in production, serving millions of members.
45- An active DDoS attack hitting payment links on a member portal. Revenue collection and member access down.
46- A proptech company needed to migrate from AWS to Azure — lower costs, better security — without any downtime on a live platform.

50## What changed
51 
52Scope it tight. Fix what matters. Document everything.
53 
54Each 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.

58## What we built
59 
60For 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.
61 
62The 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.

68## How it works
69 
70- PE portfolio companies cleared audit and compliance requirements within deal timelines
71- Full vulnerability assessment completed and remediated before due diligence exposure
72- Plain text passwords eliminated across multiple TPA platforms. MFA deployed. HIPAA credential requirements met.
73- Active DDoS attack mitigated. Member portal and payment processing restored without data loss.
74- AWS to Azure migration completed with zero downtime and reduced infrastructure costs
75- Audit-ready documentation delivered alongside every technical remediation
