So what

A10 Networks ended its year on a high note, bringing in record revenue of $230 million for the full year and a quarterly record of $64 million, which exceeded the company's ownguidance.

Management said that the revenue growth was fueled by "strong demand" for the company's security solutions and A10's ability to expand its businesses from cloud and service providers, and web-scale customers.

Non-GAAP net income improved as well to $2.3 million for the quarter, or $0.03 per share, which was up from a loss of $0.06 in the year-ago quarter.

In a press release, A10 Networks CEO Lee Chen said,"We also continued to drive leverage through our operating structure to make significant improvements in our bottom-line results, while at the same time, investing in key areas of our business."

A10's U.S. revenue jumped by 11% in 2016,and the company exceeded its own security revenue guidance. Security revenue is expected to continue to grow in the coming quarters and A10 expects the segment to make up 20% of its total product revenue in 2017.

Now what

Management said on the earnings call that A10 is on track to expand profitability this year, but also warned that there could be some quarterly volatility as well.

"And so our expectation is as we move through 2017, that the general trend will be upward, which is not the same as saying that each quarter will be upward.So there will still be some volatility around it, but the general trend on gross margin should be improving on the product side," said Greg Straughn, A10's chief financial officer.
