Twitter has agreed to acquire online security specialist Dasient as the firm continues to bolster its product portfolio.
In a post on the company blog, Dasient management confirmed the company had agreed to be bought by Twitter and would be moving to the company's so-called revenue engineering branch.
Specialising in web-based security, Dasient's platform allows web publishers and advertising networks to scan content and block malware activity and attack sites.
In making the deal with Twitter, the company will be shutting down its other operations and will no longer be accepting new customers.
"Over the last year, we have been very active in securing the ads and content of some of the industry’s largest ad networks and websites," the company said in its announcement.
"By joining Twitter, Dasient will be able to apply its technology and team to the world's largest real-time information network."
Terms of the acquisition were not disclosed.
The Dasient deal comes just days after Twitter revealed an agreement to acquire news aggregation service Summify. In announcing the deal, Summify said that it would be working to better-connect Twitter users with sites and news items.
While Twitter has been making moves to expand its operations, other microblogging services are encountering new restrictions.
The Chinese government is said to be considering a programme that will force users in the country to sign up for microblogging platforms with their legal names rather than nicknames or aliases.
