As it celebrates its 10th anniversary this week, Okta, the $9 billion security and identity management company, has released its annual report of the fastest-growing work apps of the year.

This is the fifth year that Okta, which now has over 100 million users, has released this annual report. Okta provides identity and access management solutions — in other words, it helps companies manage who has access to which apps. By that token, it's in a pretty good position to track which apps are on the rise in the workplace. 

Okta CEO and co-founder Todd McKinnon says that the company has been able to track the rise of Slack, which went from zero to a fixture of the enterprise software space in only a few years. Now, Slack is listed on the report as one of the most popular apps of 2018.

"It's interesting to talk about and interesting for people think about their technology landscape," McKinnon told Business Insider. "We really started doing this report because customers were asking for it. A customer might say, 'We've grown really fast. What do other customers that are twice as big use?'"

In the past year, McKinnon has seen a greater emphasis on security-based work apps than in the past.

"People are using more security technologies," McKinnon told Business Insider. "Everyone's worried about making headlines and having employees get phishing attacks."

McKinnon says that compared to 10 years ago, people have lost trust in technology, thanks to an increasing number of privacy and security breaches in the news. That's why demand for security apps is on the rise. 

"In the last ten years, there's been more technical progress, mobile phones, all that," McKinnon said. "What's changed is that people trust technology less now. We want to bring trust back to technology. That's what we're trying to do."

Here are the 10 fastest-growing apps of 2018, according to Okta:

Teem, recently acquired by WeWork, helps companies manage meetings and book conference rooms. What's more, it can manage visitors and track workplace analytics about how workspaces are being used. 

$7.79 billion RingCentral is a phone, team messaging and video conferencing system. This all-in-one system can be used to help teams collaborate and to help companies communicate better with customers.

Freshservice is an IT service desk product from the company Freshworks. It can be used to manage IT incidents and provide support via email, a self-service portal, phone, chat, or in person.

Atlassian has a wide range of products that companies use for software development, project management, teamwork, and code quality. The $24.5 billion company is most known for its project management and bug tracking software Jira, but also offers tools like code-sharing service BitBucket and document collaboration tool Confluence.

Adobe, the $123.76 billion computer software company, has a wide range of software products used for multimedia and creative projects, including Photoshop, Premiere, and Illustrator. It also offers software for digital marketing and managing documents.
