You might think that with heavyweights like Microsoft, Salesforce and VMware gunning for its business, a startup like Okta would be playing defense. Instead CEO Todd McKinnon says his main concern is maintaining the IT security company’s ample gross margins and spending discipline.

Okta (pronounced “ahk-tuh”) helps big companies like Adobe and Twitter give their employees a single username and password to log into all of their workplace apps and make sure their credentials are secure, a business that has become hugely important as both hacking threats and cloud-based apps have proliferated.

The company nearly doubled its valuation to $1.175 billion in a $75 million round earlier this month from existing investors that include Andreessen Horowitz, Sequoia Capital and Greylock Partners.
