(Bloomberg) -- Zoom Chief Executive Officer Eric Yuan pledged that his company will meet the highest security standards, seeking to put millions of new users at ease after numerous security lapses on the video-meeting application.

Zoom Video Communications Inc. is launching a feature called Security that sets all privacy settings to their highest level, including putting passwords on meetings and employing waiting rooms that force meeting hosts to filter conference attendees, Yuan said Wednesday on a webinar. The San Jose, California-based company is planning to roll out upgraded encryption for its video calls and meeting rooms for large webinars.

“Zoom is safe compared to peers,” Yuan said. “We are determined to do better and hold ourselves to the highest standard on security and privacy.”

Zoom has never sold user data and never will, he said.

The security webinar was part of Yuan’s mea culpa campaign to rebuild trust with the more than 200 million users who’ve turned to Zoom amid the Covid-19 pandemic. Zoom was sued by a shareholder Tuesday who alleged the company fraudulently concealed its lack of end-to-end encryption and its data transmissions to Facebook, just one of several lawsuits that have sprouted during the revelations about the software maker’s privacy problems. Earlier Wednesday, Zoom announced it had hired Facebook Inc.’s former security chief Alex Stamos as an adviser and formed a security council to help guide its next steps. Before its recent surge in popularity, Zoom had focused primarily on corporate communications.

“I am attracted to difficult problems, and this creates some doozies,” Stamos, now director at Stanford University’s Internet Observatory, wrote Wednesday in a blog post. “The adaptation of a successful enterprise collaboration tool into virtual classrooms, virtual doctor’s offices and a myriad of other applications (including at least one virtual Cabinet Room) has created privacy, trust and safety challenges that no company has ever faced.”

The company, Stamos added, “has some important work to do in core application security, cryptographic design and infrastructure security, and I’m looking forward to working with Zoom’s engineering teams on those projects.”

Despite the recent barrage of negative publicity, Zoom’s shares gained 10% to $125.56 at 2:39 p.m. in New York and have jumped 82% this year.
