The global cyber war continues to rage, engulfing political parties and national leaders of all types. Corporations also are falling victim to digital espionage, as cyber thieves hack into precious informational assets.

Below, we examine one of the best growth plays on the worsening scourge of digital hacking. First, let's look at the latest developments on the cyber battlefield.

Anyone who has watched The Sopranos knows that the early "songbirds" get the best plea bargain deals. This fact of jurisprudence probably explains why Donald Trump's former national security adviser, Michael Flynn, on Thursday offered to testify before congressional committees investigating links between the Trump team and Russia. In return, Flynn demanded immunity.

The crux of the Flynn scandal is Russia's meddling in the 2016 presidential election, through the hacking of Democratic party databases and emails and the creation of websites that spread "fake news" and derogatory information about Trump's Democratic challenger Hillary Clinton.

The field of cyber security is rife with investment opportunities, with Silicon Valley giants such as Cisco Systems (CSCO) and Oracle (ORCL) dominating the landscape. These megacap tech stocks are solid investments but the problem is, they're a bit pricey now as the stock market hovers at lofty valuations. For market-beating growth, a shrewd move is to invest in a smaller, lesser-known player with Washington Beltway contacts and a diverse client base.

That description fits ManTech International (MANT) . With a market cap of $1.34 billion, ManTech provides cyber security products for national security agencies in the U.S. and internationally. As a midcap, ManTech should confer healthier capital appreciation than its giant peers.
