Insights

Managed IT Synergy COS offers end-to-end technology management including cybersecurity and physical security, presenting a compelling opportunity to upsell managed services, MSP partnerships, and integrated security solutions to Wisconsin businesses currently relying on disparate vendors.

Acquirement Signal Historical acquisition of Attivo Technologies indicates a growth strategy through acquisitions; align outreach around complementary security, print management, and IT services capabilities that could merge well with COS's expanded portfolio.

Mid Market Focus With 11-50 employees and revenue in the mid-range, COS targets small to mid-size businesses in Wisconsin; tailor sales motions for regional SMBs seeking consolidated IT, security, and print management under one trusted provider.

Print and IT Cross-Sell COS has a background in managed print alongside IT services; there is potential to cross-sell print optimization, document security, and workflow automation to current IT clients, expanding service stickiness.

Industry Positioning As a long-established Wisconsin IT services firm with a track record of customer success, position COS as a local, reliable partner for security-compliance initiatives, disaster recovery planning, and technology modernization to regional SMEs.
