Winxnet, a Portland IT consulting and outsourcing firm, has acquired InfoSecurus, an information security firm, also based in Portland.

The acquisition, effective April 1, was announced Tuesday in a news release from Winxnet. The sale price was not disclosed.

Winxnet CEO Chris Claudio said the addition of InfoSecurus’ expertise strengthens Winxnet’s ability to thwart cyber-attacks, which are becoming increasingly sophisticated and more frequent. The company provides IT services to many organizations throughout New England and the Southeast, and has a strong concentration in the health care and municipal sectors.

“By bringing InfoSecurus’ expertise into Winxnet, we further position ourselves to be the one resource organizations can turn to when they are looking for a partner with a proven track record for keeping information safe,” Claudio said in the release.

The merger deepens Winxnet’s bench in the areas of information security and management services, including penetration testing, vulnerability assessments, risk assessments and security training as well as managed security services such as real-time network intrusion detection, host intrusion detection, vulnerability management and compliance reporting.

Through the acquisition, Eugene Slobodzian, president of and founder of InfoSecurus, assumes the role of Winxnet’s vice president of security. Three other employees of InfoSecurus will be integrated into Winxnet’s staff as needed, according to Claudio.

In 2013, Winxnet was named to Inc. magazine’s 5,000 list of fastest-growing companies, based in part on revenues that increased 109 percent from 2010 through 2012.
