Abacus

Abacus provides managed IT and cybersecurity services to financial services firms and healthcare organizations. Its financial clients include hedge funds, private equity and private credit firms, asset managers, registered investment advisers, brokerage firms and family offices, from emerging managers to global enterprises.

The main offering for financial firms is AbacusFlex, a subscription service sold in tiers that bundles multi-cloud IT operations, endpoint and network security, continuous threat monitoring, and governance frameworks mapped to SEC, FINRA, FCA, DORA and New York's 23 NYCRR 500 rules. Firms can hand over their whole IT environment or keep an internal team and use Abacus for tooling, escalation and security work. Each client gets an onboarding project manager, a client experience manager and 24-hour service desk support. Abacus also sells cybersecurity advisory, incident response, managed AI services and professional projects, and helps compliance staff answer audits and due diligence questionnaires.

Abacus started in San Francisco in 2004 and now has its headquarters in New York, with an EMEA base in London and offices across the US, the UK and the UAE. The company says it supports more than 800 financial clients. Pricing is by subscription tier and is not published.
