The IT Challenges Accounting Firms Face

Busy seasons, sensitive data and strict rules put real pressure on your technology.

Busy Season Can’t Have Downtime

When returns are due, every hour counts. A slow server or a failed backup in March costs far more than it would in July.

Client Financial Data Is a Target

Tax returns, Social Security numbers and bank details make accounting firms an attractive target for hackers and identity thieves.

Rules Require Safeguards

The FTC Safeguards Rule and IRS guidance expect tax professionals to protect client data, including having a written information security plan.

Remote & Seasonal Staff

Seasonal hires and staff working from home all need secure, reliable access, set up quickly and removed cleanly when the season ends.
