Nehemiah Security acquires New Hampshire research and development company

Tysons Corner-based Nehemiah Security, a supplier of cybersecurity software and services, has acquired Siege Technologies, an advanced research and development company based in New Hampshire.

Nehemiah officials say the acquisition will bolster the company's ability to protect its clients’ most valuable digital assets. The deal represents Nehemiah’s fourth cybersecurity acquisition since 2015.

Financial details of the acquisition were not announced.

“As we continue to expand our cybersecurity solution offering, Siege will play an invaluable role in research and development,” Paul Farrell, the CEO of Nehemiah, said in a statement. “Our plan is to invest in Siege’s growth and have them continue to operate just like they have over the past eight years.”

Nehemiah cited as an example of Siege’s innovative technology a threat quantification engine, which is engineered to replicate a network configuration at a high level of detail within minutes and mathematically predict the effects of offensive and defensive cyber operations.

The company said the threat quantification engine, available commercially in December, gives companies insights on how their networks would stand up to a wide range of attacks.
