NEW YORK (TheStreet) -- Shares of FireEye (FEYE) - Get Report are getting a boost after Imperial Capital highlighted the company’s “significant progress” when upgrading its rating on the name. California-based FireEye is a provider of cybersecurity solutions.

UPGRADE: Imperial Capital analyst Michael Kim upgraded FireEye to Outperform from In-Line this morning in a note to investors, citing a favorable risk/reward at current share levels. The stock trades at the lower valuation end of similar high-growth security vendors, Kim tells investors in a research note. He believes FireEye is making "significant progress" on driving higher sales productivity and margin expansion. Ramping global adoption of the company’s platform has made FireEye a top-tier security vendor, Kim argues. He raised his price target for shares to $55 from $45.50.

NOT ALONE: Kim is not alone in recommending stocks in the cybersecurity space. Analysts at Piper Jaffray and Wells Fargo last week highlighted security names that they view as attractive investments. CyberArk Software (CYBR) - Get Report, Barracuda Networks (CUDA) and Fortinet (FTNT) - Get Report were among the stocks recommended by the firms. Piper Jaffray analyst Andrew Nowinski said the recent pullback in the sector is an attractive buying opportunity. Stocks with the most attractive valuations include Barracuda, CyberArk, Fortinet and Palo Alto Networks (PANW) - Get Report, he told investors last week. Wells Fargo analyst Gray Powell last week upgraded Israel-based CyberArk to Outperform from Market Perform saying the company's billings growth as well as its sales and marketing efficiencies are "exceeding peers by a wide margin.

HACKS CONTINUE: High-profile cyber attacks continue with the Internal Revenue Service yesterday raising the number of accounts that were compromised in a data breach earlier this year. In May, the IRS revealed that 114,000 tax accounts through its "Get Transcript" application were exposed to thieves. Yesterday, the agency said a recent review revealed approximately 220,000 additional tax accounts may have been breached, bringing the total number of victims up to 334,000.

Shares of FireEye are up 56c to $44.21 in early trading. CyberArk is up 13c to $60.06 while Proofpoint (PFPT) - Get Report, a company focused on securing email communication, is up 16c to $65.06.
