Westerville's Columbus-Suburb IT Partner
Managed IT and cybersecurity for Westerville's manufacturers and data-center equipment suppliers, sponsor-backed operators, corporate-services firms and the law and accounting practices along the Columbus northeast corridor.
Westerville is one of Columbus's largest northeast suburbs, a mix of corporate operations centers, Vertiv's global headquarters and the precision and electrical-equipment suppliers that orbit it, Otterbein University and a dense professional-services base serving Franklin and Delaware counties. Manufacturers here face customer security reviews scaled to the data-center and industrial customers they sell into, and the sponsor-backed operators along I-270 face diligence expectations scaled to the buyer, not to headcount. Atticus Rowan is built for that profile.
Why Westerville-area employers choose us
Westerville's employer base, data-center equipment and precision manufacturers, sponsor-backed operators, corporate services, law and accounting, operates under customer, carrier and diligence scrutiny that does not scale down for firm size. Our practice is designed for that profile, delivering documented controls and evidence rather than aspirational policy.
Response time in Westerville: Remote-first from our Tiffin HQ. Most routine work resolves remotely within 30 minutes during business hours. On-site engagements in Franklin County are scheduled in advance for hardware, cabling and critical incident response.

How we work with Westerville industries
Manufacturing
Precision manufacturers, electrical-equipment suppliers and specialty-product firms in the Westerville corridor, many of them selling into the data-center supply chain anchored by Vertiv's headquarters, operate under customer and carrier expectations that have tightened every year. Our manufacturing approach builds control environments that segment production from corporate, protect OT and produce the documented evidence customer security reviews and cyber insurance carriers expect.
Private-equity portfolio companies
We support a lower-middle-market PE portfolio company we carved out from its publicly-traded industrial-services parent operator, building the standalone IT environment, operating as the post-close MSP and producing the reporting cadence sponsors expect. That experience directly informs our engagement model for Columbus-metro operating partners and the portfolio CEOs running industrial and business-services companies along the northeast corridor, from pre-close diligence through the 100-day plan.
Professional services (legal, accounting)
Law firms, accounting firms and corporate-services firms in Westerville hold sensitive client data under professional and liability obligations. Our professional-services work emphasizes matter-level or client-level access segregation, phishing-resistant authentication, data-loss prevention and documented evidence professional-liability carriers increasingly require at renewal.
Technology and SaaS
Columbus's technology corridor, SaaS firms, engineering services and data-center technology operators, faces customer security reviews that escalate rapidly as the first enterprise deals land. We guide product-led companies through SOC 2 readiness, vendor-risk programs and documented evidence enterprise procurement expects.

Common questions, Westerville
We supply the data-center build-out and our customers now send security questionnaires. Can you help?
Yes. Data-center and hyperscale customers run structured vendor-review programs that expect a documented cybersecurity program, MFA across systems touching customer data, endpoint protection with central visibility, tested backups and evidence of operation. We map each question to the control already in place (with documentation), flag partial coverage with a remediation plan and produce a response package procurement accepts on first review.
A prime flowed NIST 800-171 down to our contract. Where do we start?
With scoping. Identify where Controlled Unclassified Information actually lives, then build the System Security Plan, assess the 110 controls and document the gaps in a Plan of Action and Milestones. Most suppliers need 90-120 days to reach a defensible self-assessment. We support 800-171 readiness; we are not a CMMC C3PAO.
Are you built for the Columbus-metro professional-services tier?
Yes. Our practice is designed for the client-confidentiality and professional-liability expectations specific to law firms, accounting firms and corporate-services firms. Each has a different control focus and we design accordingly.
Our cyber insurance questionnaire got longer this year. Can you help us answer it?
Yes. We map each question to the control already in place (with documentation), identify partial coverage (with a remediation plan) and produce a response package the carrier accepts on first review. The deliverable improves next year's premium and your posture.
We're approaching a PE sale. What should we have in place for diligence?
Documented cybersecurity program mapped to NIST CSF 2.0, tested backup and recovery, cyber insurance in force, no hidden incident history, vendor-risk inventory and a prioritized roadmap for identified gaps. We have supported a full carve-out from a publicly-traded industrial-services parent and operate as the post-close MSP, so we know what the operating partner reads first.
SOC 2, can you help us pursue it?
Yes. We guide companies preparing for SOC 2 Type I and Type II audits, building the control environment, operating it long enough to produce the evidence the auditor needs and coordinating with the SOC 2 audit firm. We are not a SOC 2 audit firm ourselves; we are the MSP that makes the audit reach a clean opinion.
