On this page

Our Washington, DC client, described rather than named

The client is an intellectual property law firm based in Washington, DC. We describe the firm on this page and do not name it, and what we say about the engagement stops at the four areas of work it has covered. Each area has its own page on this site setting out what that service involves.

Software development

Our software development services page sets out the five stages a build runs through, from discovery to support.

IT and Microsoft 365

Our Microsoft 365 consulting page covers tenant governance and access review, and our IT consulting page covers assessments and plans.

Security

Our cybersecurity services page groups the work the way a buyer arrives: assess, build, operate and comply.

Website and digital

Our web development services page separates a template build, a custom marketing site, a web application and a platform or portal.

What those links are. Each one describes a service in general. None of them is an account of the work we did for the firm, which this page limits to the four areas named above.

Where our office is, relative to the District

Our headquarters is in the Tysons business district of McLean, in Fairfax County, Virginia. It sits inside the National Capital Region, which Title 40 of the U.S. Code defines as the District of Columbia together with named counties in Maryland and Virginia, Montgomery and Fairfax among them, and the cities inside their combined area (40 U.S.C. 8702). So the office is in the region, but not in the District.

Our government IT services page explains why that matters for federal work: we can be at an agency's facility for the working sessions that move a requirement forward, and we are in the same time zone for the whole working day.

Figure 1. The National Capital Region: the District, the county our office sits in, and a Maryland county we serve from it

Schematic of the National Capital Region as 40 U.S.C. 8702 defines it: the District of Columbia, where our client, an intellectual property law firm, is based and where Sthenos has no office; Fairfax County, Virginia, where our Tysons headquarters is; and Montgomery County, Maryland, where we serve clients from Tysons and have no office.

Caption: a schematic, not a map, and nothing in it is drawn to scale. The region is as 40 U.S.C. 8702 defines it, and the other counties and cities that section names are not drawn. Tysons is in Fairfax County, as our Tysons page states.

Software and AI development for Washington, DC organizations

What Sthenos builds does not change at the District line: custom software development, AI and agentic systems, cloud migration and cloud platforms, legacy system modernization, data engineering, government IT services and staff augmentation. On the AI side, our AI and machine learning page orders the work the way it actually sequences, and these are the groups it names:

  • Strategy and use case selection: where AI earns its place, and where a rules engine would do the job more cheaply
  • Data readiness and pipelines: inventory, access, quality and lineage
  • Retrieval augmented generation: answers drawn from your own documents and records, carrying their sources
  • Agents and automation: systems that take action across your tools, sold on our agentic AI page
  • MLOps and monitoring: the monitoring that tells you a model has quietly stopped working
  • AI governance and security: access control, audit logging, approval gates and retention

An AI feature inherits every obligation that already binds the system it sits inside, which is why governance sits on the same list as the models. If you run a law firm, our legal industry page covers software and IT for law firms and legal teams, including confidentiality and privilege.

Cloud services for Washington, DC organizations

The cloud services Washington DC organizations can contract from us are the ones set out on our cloud computing and cloud migration and optimization pages. Those pages order the groups the way the work usually sequences, and six of them are below.

Strategy and landing zonesThe account structure, identity, network boundaries, logging, guardrails and cost model every later workload inherits.
MigrationMoving the workloads themselves, in waves, with a rollback point per wave.
Cloud native and DevOpsManaged services instead of self-run equivalents, and pipelines that deploy without a person in the loop.
Security and complianceIdentity and access design, encryption, logging an auditor can read, and configuration review against a published benchmark.
FinOps and cost governanceMaking the bill legible before trying to shrink it: tagging, rightsizing, commitments and a shutdown schedule.
Managed cloud operationsRunning the environment after go live: incident, problem, change and release management, and the help desk tiers.

A federal agency in the District asks the cloud question in a different order. FedRAMP is the Government-wide program that provides a standardized, reusable approach to security assessment and authorization for cloud computing products and services that process unclassified information used by agencies (44 U.S.C. 3608). The authorization attaches to the cloud service, not to the integrator who builds on it, and the agency still issues its own authorization to operate (44 U.S.C. 3613). A consultancy can build on an already authorized service and assemble the evidence, but it cannot grant you an authorization to operate. We hold no attestation of our own against FedRAMP or any other framework, and we are not SOC 2 attested.

How a project runs

It starts with a call to 301-793-3980 or the requirement sent through our contact page, and we will tell you whether it is work we should be doing. A build then runs through the five stages published on our software development services page, and each stage ends in something you can check.

  1. DiscoveryThe problem, the constraints and the success criteria are mapped before a line of code. It ends with a written scope and a costed roadmap.
  2. DesignThe decisions that are expensive to reverse: data model, service boundaries, hosting, failure behaviour, and an interface that fits your users.
  3. BuildSenior engineers ship in short, reviewable increments, with automated coverage written alongside the feature rather than after it.
  4. LaunchHardening, testing and a controlled release, covering environments, the release pipeline and the rollback path.
  5. SupportMonitoring, maintenance and a roadmap tied to business outcomes, run by the people who built the thing.

Federal agencies and prime contractors in the District

If you buy for a federal agency or a prime contractor, read our government IT services page before this one. It sets out how agencies and primes can buy from us, the set-aside path and the codes it actually covers, and our registration details. We keep those details on that one page rather than repeating them here.
