Columbia-based Tenable to partner with Siemens Tenable, a Columbia-based cybersecurity company, announced Tuesday a strategic partnership with Siemens to develop programs that will protect increasingly vulnerable critical infrastructure, such as oil refineries and energy grids. Through the partnership, the companies are launching Tenable’s “Industrial Security,” which Germany-based Siemens will offer to its energy, oil and utility company clients. The deal expands Tenable’s reach into a large — and growing — market. While they accounted for a relatively small number of cyberattacks years ago, such systems are now the target of about a third of attacks, said Tenable’s chief financial officer, Steve Vintz.

To date, the company has focused on software that continually monitors large data networks for vulnerabilities and threats. Adidas, BMW, MasterCard and Microsoft are among Tenable’s clients. The partnership opens a new client base to Tenable while pairing it with a partner with astrong hold in the market. Siemens, a global engineering and technology company, is a leading provider of the technology systems used to monitor and manage critical infrastructure. Tenable has been growing steadily since raising $250 million in 2015. The company has expanded to new international offices and has a staff of over 1,000 people in 20 offices worldwide.

—Sarah Gantz Twitter doubles character limit for (nearly) everyone Twitter says it’s ending its 140-character limit — and giving nearly everyone 280 characters. Users tweeting in Chinese, Japanese and Korean will still have the original limit. That’s because writing in those languages uses fewer characters. The company says 9 percent of tweets written in English hit the 140-character limit. People end up spending more time editing tweets or don’t send them out at all. Twitter hopes that the expanded limit will get more people tweeting more, helping its lackluster user growth. Twitter has been testing the new limit for weeks and started to roll it out Tuesday. The company has been slowly easing restrictions to let people cram more characters into a tweet. It stopped counting polls, photos, videos and other things toward the limit. Even before it did so, users found creative ways to get around the limit.

This includes multipart tweets and screenshots of blocks of text. Twitter’s character limit was created so that tweets could fit into a single text message, back when many people were using texts to receive tweets.

—Associated Press Disney ends L.A. Times ban after backlash The Walt Disney Co. lifted its ban of Los Angeles Times reporters and critics from its press screenings on Tuesday after a widespread backlash prompted several media outlets to announce their own boycotts of Disney movies. In a statement Tuesday, Disney said it was restoring access to the newspaper after “productive discussions with the newly installed leadership” at the Los Angeles Times. Disney had barred the Times from its screenings after the paper published a two-part investigative series on the company’s business dealings in Anaheim, Calif., where Disneyland is. The newspaper is owned by tronc inc., which also owns The Baltimore Sun. The ban’s withdrawal ended an unusual clash between what may be Hollywood’s most powerful studio and the media outlets that regularly write about its movies. Disney’s punitive measures against the Times led to many outlets refusing advance coverage of the studio’s films.
