Symantec’s announcement Thursday that it would acquire storage management vendor Veritas Software for $13.5 billion won praise from analysts who noted that Symantec would now become the largest supplier of backup, recovery and archiving software.

In the deal, fast-growing Symantec, with its 6,000 employees and annual sales of $1.9 billion, would swallow up Veritas, with its 6,700 employees and $1.8 billion in sales. Each company has more than $2 billion in cash. Symantec has been growing by about a third each quarter, Veritas by less than half that.

Symantec, whose consumer anti-virus sales have funded its push into the corporate market for some time, “is re-inventing itself into a major enterprise security management vendor with acquisitions and a new marketing theme, but they have some gaps,” said Steve Hunt, vice president and research director for security at Forrester.

“Veritas is a successful backup and archiving vendor looking for a way to penetrate the security market which has growing needs for such software,” says Hunt.

Symantec CEO John Thompson, in a conference call with analysts, explained the rationale behind the merger. “Our customers’ recognition that while the regulatory environment requires increased information security, future business opportunities require that more and more information be made available to a greater amount of people,” Thompson said.

“This dichotomy is driving the obvious convergence between securing the infrastructure and ensuring information availability. Combining Veritas and Symantec strengthens our ability to serve the needs of customers with security and availability solutions, thereby securing the integrity of their most valuable asset - information,” Thompson said.

He added that both Veritas and Symantec in the coming weeks would explore possibilities in integrating storage and security protections to automate security processes. Symantec will also consider the possibility of bringing storage technologies into the consumer arena as well.

Veritas CEO Gary Bloom, who will join Symantec as vice chairman and president, said one driver toward combining the two companies is that "our customers are looking to consolidate suppliers and eliminate complexity." He said he anticipated the Veritas shareholders would be supportive of the acquisition, which faces SEC approval as well.
