Solutions
What we deliver
A niche set of practices focused on the problems public sector organizations face most: aging systems, manual processes, rising cyber risk, and pressure to do more with less.
Replace paper and email with working systems
Low-code and no-code platforms let agencies build the applications they need in weeks, not years. Instead of hand-coding every screen and rule, teams assemble apps from ready-made building blocks, model the workflow visually, and add custom code only where the mission requires it. Grey Sentry designs, builds, and governs these solutions so they stay secure and maintainable as they grow.
For professional developers
Visual modeling speeds up the routine work, while developers extend apps with scripts, APIs, and integrations for complex requirements.
For business users
Program staff configure forms, approvals, and simple apps through guided templates and rules, with IT setting the guardrails.
What we deliver
Low-code application development
Case management, intake, and tracking applications built on enterprise platforms and released in short, iterative cycles.
Workflow & process automation
We map how work flows today, then replace email chains and spreadsheets with automated routing, approvals, and alerts.
Systems integration
Connect new apps to existing HR, finance, identity, and records systems through platform connectors and APIs.
Legacy modernization
Rebuild aging custom applications on a supported low-code platform to cut maintenance cost and technical debt.
Citizen developer governance
Standards, review gates, and training so business users can build safely without creating app sprawl or security gaps.
Digital services & reporting
Section 508 compliant portals and forms, plus dashboards that give leadership a live view of operations.
Why agencies choose low-code
Platforms we build on
Retire technical debt safely
We modernize legacy systems and infrastructure in planned, low-risk increments, keeping services running while the platform underneath changes.
Cloud migration
Assessment, planning, and migration to FedRAMP authorized cloud environments.
Application modernization
Re-platform or re-architect legacy applications into maintainable, modern services.
DevSecOps & CI/CD
Automated build, test, and security scanning pipelines that speed up safe releases.
Network & data center services
Consolidation, operations and maintenance, and performance monitoring.
Practical AI with guardrails
We focus on AI use cases with a measurable payoff and build them with the transparency, testing, and oversight that federal AI policy expects.
Predictive analytics
Forecasting and risk models that help programs plan resources and spot problems early.
Document intelligence
Extract, classify, and summarize data from forms, contracts, and case files.
Intelligent automation
Combine machine learning with workflow automation to clear repetitive, high-volume work.
Robotic process automation (RPA)
Software bots that handle rule-based tasks such as data entry, reconciliation, and report generation.
Chatbots & virtual assistants
Conversational tools that answer common questions for employees and the public, and hand off to staff when needed.
AI governance
Use case inventories, risk assessments, and monitoring aligned with the NIST AI Risk Management Framework.
Know your risk. Stop the threat.
We help agencies understand where they are exposed, reduce that risk in priority order, and catch and contain threats quickly when they appear.
Risk Assessment & Management
Enterprise cyber risk assessments
A top-to-bottom look at your systems, data, and cloud footprint that ranks weaknesses by mission impact, not just technical severity.
Security program maturity reviews
We measure your cyber program against NIST, FISMA, and peer agencies, then show the practical steps to the next maturity level.
Zero Trust strategy & roadmap
Identity-centered architecture plans aligned with OMB M-22-09 and the CISA Zero Trust Maturity Model, phased to fit your budget.
Resilience & continuity planning
Continuity and recovery plans, tested through tabletop exercises, so critical services keep running during a disruption.
Third-party & supply chain risk
Vendor risk reviews and supply chain controls based on NIST SP 800-161, so outside partners don't become your weakest link.
RMF & ATO support
Security assessment and authorization, ISSO support, and audit readiness under NIST SP 800-37 and 800-53.
High Value Asset (HVA) assessments
In-depth reviews of your most critical systems following the CISA HVA program methodology, with a clear remediation plan.
Strategic cyber consulting
Senior advisors who help leadership set security priorities, plan budgets, and brief oversight bodies with confidence.
Threat Detection & Response
SOC optimization
Tune tools, alert rules, and playbooks so your analysts spend time on real threats instead of noise.
Managed detection & response (MDR)
Around-the-clock monitoring, triage, and containment by our analysts, plus continuous monitoring (ISCM) reporting for leadership.
Incident response
Response plans, on-call support, and after-action reviews that shorten the time from detection to containment.
AI-assisted threat detection
Machine learning and behavior analytics that surface unusual activity traditional rules miss.
Endpoint & cloud security
Protection for laptops, servers, workloads, and cloud accounts against malware, misuse, and intrusion.
Penetration testing & red teaming
Realistic attack simulations that show how an adversary would get in, and exactly how to stop them.
Mapped to NIST CSF 2.0
Less paperwork, faster hiring
We automate the HR processes that slow agencies down, from onboarding to personnel actions, while keeping records accurate and auditable.
Onboarding & offboarding
Coordinated tasks across HR, IT, security, and facilities, triggered automatically.
Personnel action processing
Automated routing and validation that reduce errors and processing time.
HR service delivery
Employee self-service portals, case management, and knowledge bases.
Workforce analytics
Reporting on hiring timelines, attrition, and workload to support planning.

About Grey Sentry
Innovation in service of the public sector.
Founded in 2022, Grey Sentry is a woman-owned and minority-owned small business, holding SBA WOSB and SWaM certifications. Government agencies rely on us for five specialties: modernizing infrastructure, transforming how work gets done digitally, applying AI and machine learning, securing systems, and automating HR.
Our name reflects how we work. A sentry stands watch so others can focus on their mission. We take the same role for our customers: keeping systems modern, secure, and running so agencies can serve the public.
We stay deliberately focused. Rather than offering everything, we invest deeply in five practices and the people who deliver them, which lets us bring senior expertise to every engagement.
