What does a law firm founded by former NSA employees actually do differently from the practice down the street? In the case of Henault & Sysko Chartered, the answer sits right in its core specialty: national security and security clearance law. The firm, set up in 1980 in Glen Burnie, Maryland, built its name around the people who hold clearances and the agencies that grant them. That is a narrow lane, and it is not one most general-practice attorneys can credibly claim. A listing that names both a suburban Maryland address and a Washington, D.C. office immediately sets Henault & Sysko Chartered apart from a typical small practice.

The clearance work is where Henault & Sysko Chartered reads as genuinely specialised. It handles security clearance adjudications and appeals, industrial security clearance matters, and hearings tied to the NSA, along with broader counsel for the intelligence and defense communities and the government contracting that surrounds them. For a federal employee or a defense contractor staring at a clearance denial or a revocation, that is a real and often urgent problem, and the kind of thing you want represented by someone who has sat on the other side of the table. Founders who came out of the NSA bring exactly that vantage point. I find that detail more persuasive than any tagline a firm could write about itself, because it explains how the specialty took shape and why these particular lawyers can claim it.

Beyond the clearance practice, Henault & Sysko Chartered is a full general-service shop, and it does not hide that. It takes on business law, criminal defense, divorce and family law, estate and succession planning, litigation, and real estate matters. The spread is wide enough that a household in the Maryland or Washington D.C. area could plausibly use the same firm for a will, a property closing, and a contract dispute. The risk with any practice this broad is that the headline specialty carries the marketing while the rest gets lighter attention, so a prospective client with a family law or estate matter would do well to ask directly how much of that work the firm does day to day. The profile available does not settle that question one way or the other, and it would be dishonest to pretend it does.

On the people side, the picture is modest and clear. Henault & Sysko Chartered is a multi-attorney practice, and lawyers.com lists three attorneys actively working there. Three is small, which cuts both ways: a clearance client likely deals with a principal directly instead of being routed to a junior associate, while a firm of that size has natural limits on how many simultaneous matters it can carry. For the clearance niche, where the relationship with the attorney tends to matter more than the size of the masthead, the small headcount feels like a fit rather than a shortfall.

The firm keeps an office in Glen Burnie, Maryland, and a second in Washington, D.C., which lines up neatly with where its clearance clients tend to live and work. The D.C. presence is important for anyone whose hearing or agency business sits in the capital. A firm claiming to serve the intelligence and defense communities while operating only out of a suburban Maryland address would invite some skepticism; the second office answers that before it can be raised.

Reaching Henault & Sysko Chartered is straightforward, which is more than can be said for a fair number of small-practice sites. The homepage puts a phone number, a fax line, both physical addresses, and business hours where a visitor can see them without digging. For a clearance matter, where timing can be tight and a phone call beats a web form, that visibility counts. Nothing about the contact setup asks the visitor to work for the information.

What the public ratings add up to

Outside opinion lands on the positive side, though the volume is light. Henault & Sysko Chartered holds five stars across nine reviews on Birdeye and a 5.0 rating from seven reviews via the Chamber of Commerce. It is also listed on Yelp and Lawyers.com, though the review counts and ratings on those two were not available, so no guesses are made here. Henault & Sysko Chartered carries a Martindale-Hubbell award noted on Martindale.com, an honor that requires at least three reviews and a score of 4.0 or higher, and Lawyers.com records an earlier award as well. None of these are enormous sample sizes, but they point in a consistent direction, and a niche legal practice rarely accumulates hundreds of public reviews the way a restaurant might. What exists is uniformly strong.

The honest reservation is the reservation of scale, not quality. Henault & Sysko Chartered spreading itself across a specialized federal practice and a half-dozen everyday legal areas is asking a lot of three attorneys, and a client whose need falls outside the clearance lane should confirm that the firm gives that area real attention rather than treating it as overflow. That is a question the firm itself can answer in a first conversation more reliably than any listing can.

Where Henault & Sysko Chartered earns genuine confidence is the territory it was clearly built to serve. The clearance and intelligence-community work is grounded in the founders' own backgrounds, the two offices put it physically where that work happens, and the third-party feedback, modest in count, is unanimous in tone. Henault & Sysko Chartered has held that ground since 1980, which is a long time to keep a specialty this particular alive. For a clearance problem in Maryland or the D.C. corridor, the combination of specific experience, dual locations, and clean outside ratings is hard to dismiss. The general-practice side is where the published record falls short of a recommendation: nothing in the profile confirms how much divorce, estate, or real estate work three attorneys take on alongside the federal caseload, so that part of the offering stays unproven on the evidence available.
