Check Point’s plan to buy Pointsec has run into trouble, but that hasn't prevented it from buying another security company, NFR, for $20 million.

Just 41 percent of Pointsec's shareholders have accepted the offer price of $586 million, and Check Point has had to up the price to $625 million.

The deal is still likely to go through but the deadline for its completion has been extended until 8 January to allow shareholders time to ponder the new offer. In the meantime, the company has announced a separate acquisition - that of intrusion detection company NFR for $20 million. That deal, at least, looks more done and dusted.

Only last month, the acquisition of mobile technology security specialist Pointsec, which is owned by a number of investment companies, looked on track. But under Swedish law, Check Point needs the agreement of 90 percent of shareholders before the purchase can proceed.

The glitch in the Pointsec acquisition is the second time this year Check Point has had problems buying companies. Earlier this year, the company was forced to withdraw from its proposed acquisition of Sourcefire after some US government agencies and Sourcefire customers protested about the acquisition's national security implications.

As for the NFR buy, that has already received the necessary consent and Check Point will incorporate NFR's intrusion detection and prevention technologies into its own line of firewall, VPN and security management products. The result will offer a high level of intelligence, adaptability and manageability, Check Point said.

The company will also sell a stand-alone intrusion detection and prevention product that will combine NFR's product line with Check Point's InterSpect internal security gateway products.
