Tenable Network Security, of Columbia, is entering a partnership with Alexandria-based In-Q-Tel aimed at expanding Tenable’s footprint in the intelligence community.

Tenable, founded a decade ago by three local entrepreneurs who specialize in cybersecurity, helps protect businesses and government agencies from external computer threats.

In-Q-Tel is a not-for-profit investment firm that looks for private sector technologies that can be used to aid the Central Intelligence Agency and other government intelligence services.

The partnership comes on the heels of a $50 million first round of institutional investment from Accel Partners, a prominent Silicon Valley venture capital firm. It also comes a few months after the Defense Department selected Tenable to provide its software product for key defense purposes.

Prior to Tenable, co-founder and chief executive Ron Gula authored something called the Dragon Intrusion Detection System, which was acquired by Enterasys Networks. He began his career in information security while working at the National Security Agency.

Jack Huffard, another co-founder, was the director of corporate development at Enterasys Networks before joining Tenable. Now Tenable’s president, he began his career in various management and sales positions at John Hancock and Marriott.

The third co-founder, Renaud Deraison, was a creator of technology called Nessus, which helps protect computer networks from hackers and other intrusions. Now chief research officer, he released the first version of his vulnerability scanner in the spring of 1998 at age 17.

The Buzz Hears:

Bethesda native Todd Boehly, a member of the Landon School’s class of 1991, had a homecoming of sorts last week.

McLean-based Contrack International, an international construction firm, earlier this month merged with Honolulu-based construction company Watts Constructors. The purpose is to create new opportunities on federal projects, a departure from its abroad-only business model. Contrack, which was founded 26 years ago, has 10,000 employees around the world. It worked on more than $2 billion in projects for the U.S. Army Corps of Engineers in Afghanistan, as well as defense work throughout the rest of the Middle East.

Contrack chief executive Wahid Hakki, 54, who has been with the firm since 1994, has 30 years of experience in the construction industry, including work on the former Gannett/USA Today towers in Arlington. Wahid is the brother of Washington plastic surgeon Ayman Hakki of Luxxery Medical Boutique and uncle of Dannia Hakki, the co-founder of MoKi Media, a D.C. public relations firm.

Mom’s Organic Markets joins the rush of food outlets — Matchbox, Red Apron, Sweetgreens, Le Pain Quotidien, MediterraFish — in the Merrifield/Fairfax Mosaic District, opening the ninth store in the local grocery chain on Sept. 14.

“Merrifield ... perfectly fills in the gap between our Alexandria and Herndon stores,” founder Scott Nash said in an e-mail. “Mosaic will be a mecca of fantastic food.”

Making movies

Kenneth Adelman, the former director of the U.S. Arms Control and Disarmament Agency and longtime Washingtonian columnist, is a man of many interests: diplomacy, journalism, exploring and Shakespearean history.

Now he has the film bug.

Adelman, 66, is a co-producer on “Reykjavik,” which will cover the “true story” of the superpower summit between President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev in what became a key inflection point in the cold war.

The film, which is being developed by Ridley Scott’s Headline Pictures, will be directed by Michael Newell (“Four Weddings and a Funeral”) and is to star Michael Douglas as Reagan. Casting for Gorbachev is still under way, but Gary Oldman reportedly is interested, Adelman said.

Adelman, who was an adviser to Reagan at Reykjavik, where the U.S. and Soviet Union came close to a ban on nuclear weapons, said he is being called on to help ensure the firm is historically accurate. He hopes to write a book to accompany the film.

Shooting begins next spring, and the film is slated to be released in 2014.
