What Atlantic Data Security does
Atlantic Data Security (ADS) is a privately held cybersecurity services provider founded in 1993 and headquartered in East Hartford, Connecticut, with an additional Canadian presence via atlanticdatasecurity.ca. The company delivers managed security services, professional consulting, staff augmentation, and training to enterprise and SLED (state, local, education) clients across verticals including retail, financial services, healthcare, manufacturing, transportation, critical infrastructure, and system integration. ADS positions itself as a vendor-agnostic full-service provider, offering a portfolio that spans Managed Security Services, Secure Access Services built on the SASE model, Managed Firewall Services, Cloud Security Posture Management (CSPM), Incident Response, Managed Security Policy Orchestration, and automated vulnerability remediation via its Veriti partnership.
The underlying technology stack is an integration layer rather than a proprietary platform: ADS engineers are certified across more than 80 vendor technologies (Palo Alto Networks, Check Point, CrowdStrike, Zscaler, Microsoft, AWS, Fortinet, SentinelOne, Tufin, Wiz, IBM, Proofpoint, Imperva, Varonis, and others), and the firm consolidates those point tools into unified managed offerings with continuous policy orchestration and 24/7 monitoring. Core recurring revenue is generated through subscription managed security contracts and managed secure access services, supplemented by project-based professional services (assessments, pen tests, compliance audits), contract staff augmentation, and training engagements. Pricing is not publicly disclosed; deals flow through a consultative 'Talk to an Advisor' sales motion targeting enterprise buyers.
ADS goes to market primarily through direct enterprise field sales, supported by content marketing (active technical blog, whitepapers, technology summits), Google remarketing, and a partner channel leveraging its extensive technology vendor ecosystem for co-sell and integration opportunities. The company holds credibility signals including CRN MSP 500 (2023), Inc. 5000, Tufin Partner of the Year (2022), and Microsoft partner status, and it has expanded its footprint through an AWS Partner Network membership (2025) and a multi-year Hendrick Motorsports sponsorship (2025-2027). Mark Ostrowski joined as CTO in March 2026 from Check Point Software Technologies. Ownership, revenue, and funding data are not publicly disclosed.
