ATLANTA – Apptega, a leading platform helping companies easily build, manage and report their cybersecurity and compliance programs, announced today a $37 million investment from Mainsail Partners, a growth equity firm focused on investments in fast-growing, software companies. The new capital will be used to help scale the company’s award-winning platform into new markets and channels, including MSSPs.

"Partnering with Mainsail will help us not only further develop our innovative software but also support building an experienced team and brand awareness across multiple markets," said Armistead Whitney, founder and CEO of Apptega. "We are really excited to accelerate new features and capabilities that support our mission of making cybersecurity compliance easy for companies and MSSPs around the world."

With the increase in cybersecurity threats and compliance pressures, companies of all sizes are scrambling to build comprehensive cybersecurity and compliance programs that meet industry standards like SOC 2, PCI, CMMC, ISO, GDPR and many others. Historically, organizations have been using Excel spreadsheets and other manual methods to manage these requirements which number in the hundreds. Apptega is a leading platform offering 25+ cybersecurity frameworks, easy-to-follow guidance, collaboration tools, and reporting in one simple package.

"We are proud to partner with the team at Apptega to streamline the complexity of cybersecurity and compliance," said David Farsai, Partner at Mainsail.
