Auth0, a Bellevue-based cloud service providing single sign-on capabilities and security for billions of log-ins each year, today announced it has raised $30 million in funding from late-stage investor Meritech Capital Partners.

The managing director of the venture capital group, George Bischof, also has joined Auth0’s board of directors. Meritech Capital Partners has more than $3 billion in investments in private technology companies and is among the top performing venture firms.

In total, Auth0 has secured more than $54 million in Series C funding from investors, funding that will help the company offer additional security features for “modern enterprises” and potentially open the door for a few acquisitions, as well.

“Identity has become even more mission critical as businesses become increasingly digital,” Bischof said in a press release. “In our dozens of calls with customers, it was clear that Auth0’s value proposition is resonating in the market. Developers can leverage Auth0’s extensible and easy to integrate identity platform and free up their cycles to work on the core application. Auth0 subscriber adoption is exponentially expanding and we are excited to support their rapid growth.”

Auth0’s website touts having more than 1.1 billion secured monthly logins and having prevented more than 1.3 million “malicious” logins. In the past year, the company has experienced record growth, adding 1,250 new companies to its worldwide subscribers, doubled its employee headcount, opened offices in London and Sydney, and launched a new Serverless extensibility platform.
