“I am pleased with the execution in the quarter, in particular the strong performance in backup and archiving and continued momentum in hosted services and data loss prevention. In addition, we saw growth in the public sector, driven by strength across all product lines in both the civilian and defense agencies,” said Enrique Salem, president and chief executive officer, Symantec. “We’re making good progress integrating the VeriSign security business, PGP and GuardianEdge into the Symantec portfolio and all three acquisitions performed better than expected in the quarter.”

“In the September quarter, we delivered better than expected results on all of our key financial metrics. Our enterprise business closed the quarter on a strong note, generating greater than expected revenue and deferred revenue,” said James Beer, executive vice president and chief financial officer, Symantec. “We also generated another quarter of excellent cash flow from operations, up 37 percent year-over-year, for a total of $1.74 billion over the last twelve months.”

The June quarter PGP and GuardianEdge acquisitions continue to perform well, generating revenue of $15 million.
