Juniper back in the market — and how

Contact: Brenon Daly

Just nine months after Juniper Networks picked up a small stake in Altor Networks through the startup’s second round of funding, the networking giant decided Monday to take home the whole thing. Juniper will hand over $95m in cash for the rest of the virtual firewall vendor. (Altor had raised around $16m in backing, including the undisclosed investment from Juniper.) At the time of the investment, Juniper said it planned to develop an ‘even closer’ relationship with Altor, its primary virtualization security partner. See our full report on the deal.

The purchase of Altor stands as Juniper’s fifth acquisition this year, and brings its M&A spending to almost $400m so far in 2010. That’s fairly remarkable activity, considering that Juniper had been out of the market for a half-decade. And with the exception of its recent pickup of Trapeze Networks, Juniper’s buys have been big bets on small companies. The networking giant has paid $70m-100m each for Ankeena Networks, SMobile Systems and Altor – and we gather that all three of the target companies were running in the single digits of millions of dollars.
