At most private equity firms, there is a lack of visibility into the security operations across all their portfolio companies. In addition, portfolio companies have limited knowledge of their cyber risks and an equally limited cybersecurity budget.

Unfortunately, cybercriminals understand this Private Equity/Portfolio Company dynamic well. Many take advantage of the limited visibility and budgets to execute targeted ransomware attacks that can disrupt business operations and damage brand reputation.

Unless you’re prepared to defend against modern ransomware threats, your portfolio companies could be locked out of critical systems and applications for days. The resulting downtime can cost your firm $225K per day in downtime costs alone.
