BSC Partners is the M&A cyber advisor for lower middle-market and middle-market private equity firms. We run cyber diligence that tells deal teams what they actually need to know and then rapidly fix the critical findings post-close.
Partner Led
Every engagement. No junior associates running fieldwork.
4D Framework℠
Discover. Diligence. Develop. Divest.
What most providers call cyber diligence is a traditional security assessment with a deal label on it. It's too slow and out of touch with what deal teams actually care about.
The reports you're used to getting are mapped to corporate frameworks that were built for a CISO running a security program and not a deal team pricing a transaction. Same checklists. Same scans. Nothing that carries weight in the transaction.
The output is a list of technical issues stamped with severity ratings: "Critical," "High," "low." Critical to who? Critical against what threshold? Nothing in the report tells the deal team which findings carry real downside exposure. They are left translating cyber findings into deal terms on their own.
The diligence team delivers the report and walks away. You inherit a list of issues the portfolio company's IT team -- the same team that caused the issues -- is now expected to fix. By the next board meeting the findings are still open and remediation has become someone else's problem.

what we built instead
Enterprise methodologies applied to deals they weren't built for. Long control checklists with no view of what matters.
We focus diligence on the cybersecurity controls directly linked to losses. Not every control gap on the framework checklist. Not every theoretical vulnerability. We assess only what matters.
Findings rated "Critical / High / Medium / Low" by security practitioners with little deal experience.
We quantify cyber the way deal teams model other operating risks -- translated into financial impact and compared to the deal economics.
Report delivered, advisor disappears, portco's small IT team inherits the cleanup.
We don't hand off the report and disappear. Our Rapid Remediation Team™ closes out the material findings and brings the portfolio company up to a risk profile the sponsor is comfortable with.
how we do it

Actionable perspectives on cyber risk, governance, and deal strategy. Stay informed with the latest thinking from our team and industry experts.
WORK WITH US
Lower and middle-market acquisitions inherit material cyber exposure due to smaller IT teams, older systems, and few cyber controls. These deals are the least likely to get cyber diligence because traditional providers price and scope for enterprise.
BSC was built to close that gap. Fast enough to keep pace with your deals, scoped tight enough to not add complexity. We screen for material risk in days, not weeks, and work as an extension of your team to fix the issues.
