Cisco Systems just announced that it will buy Duo Security, an Ann Arbor, Mich.-based provider of access security and multi-factor authentication software, for $2.35 billion in cash.

The big picture: This comes less than 24 hours after Reddit disclosed that its own two-factor authentication solution failed, because hackers intercepted some mobile text messages that contained verification codes.

  • Duo had raised around $120 million in VC funding, most recently at a $1.2 billion valuation, from firms like Benchmark, Meritech, Lead Edge Capital, Cisco, Workday, Redpoint Ventures, Geodesic Capital, Index Ventures and True Ventures.

Between the lines: Duo's solution begins with 2FA, but goes deeper. One of the current hip phrases in security is Zero Trust, where you continually reevaluate anything connected to a network before allowing it to do anything new.

  • Duo is in that space. So rather than trust any computer that logs into a network to access anything on the network, you continually make sure the things that are logged on are supposed to be there.

Democrats on Trump tax story: "This is a national security question"

House Speaker Nancy Pelosi said Monday that the New York Times report that President Trump has hundreds of millions of dollars in debt coming due within the next four years is a "national security question," and that the public has a "right to know" the details of his financial obligations.

The big picture: Democrats have already leapt on the Times' bombshell, which Trump has dismissed as "total fake news," to attack the president for allegedly paying less in federal income taxes than the average middle-class household.

Driving the news: Judge Carl Nichols on Monday unsealed his opinion, in which he concluded that the ban seeks to regulate the exchange of "informational materials" — something that's expressly exempted from the law laying out the emergency powers Trump invoked.
