The Solutions
Reduce Tax-Season Fraud Risk
Practical Fraud Prevention for Busy Tax Firms
Tax firms are prime targets during tax season because your communications involve sensitive identity details, money movement, and urgency. We help reduce this risk by strengthening identity and email safeguards and by supporting a clear, repeatable verification process staff can follow even when workloads are high.
Business Outcomes:
- Fewer fraud incidents
- Fewer near misses during peak season
- Stronger client confidence and trust
Lower Ransomware Impact & Improve Recovery Readiness
Business Continuity That Prioritizes What Matters
No one can promise zero downtime, and ransomware can be disruptive even with good preparation. We focus on limiting how far an incident can spread and building recovery steps that prioritize what matters first: communication, file access, and the systems your team needs to serve clients. We validate recovery plans so they work when needed — not just on paper.
Business Outcomes:
- Reduce downtime risk
- Clear recovery expectations
- Faster return to productive client work
Protect Client Data Without Adding Friction
Secure Access That Supports Client Trust
Tax firms hold some of the most sensitive personal and financial information. We help implement clear access controls and safer document-sharing practices so client data doesn’t drift across inboxes, desktops, or unmanaged devices.
Business Outcomes:
- Reduced data exposure risk
- Cleaner, more controlled access to client information
- Calmer, more efficient workflows
Clear Support When Time is Critical
Calm Guidance When It Matters Most
When something looks suspicious, uncertainty can spread quickly. We provide calm, clear communication and next steps so leadership can make informed decisions and staff can keep moving forward without guesswork.
Business Outcomes:
- Faster issue resolution
- Less internal disruption
- Better client experience during stressful moments
Practical Protection Built Around Deadlines
We do not lead with buzzwords.
We lead with what the firm needs: fewer emergencies, lower risk, and a recovery plan you can actually execute.
Your firm should feel steady under pressure - tax season already provides enough pressure.
FAQ
Email impersonation and account takeover are extremely common because they can lead to stolen client data, payment diversion, and fraudulent requests processed under time pressure. These attacks often look legitimate and are timed around deadlines.
W-2 fraud is typically a social engineering scam where an attacker impersonates an executive or trusted party and requests W-2s or payroll data. It works because it uses authority and urgency. Clear verification steps and restricted access to payroll data reduce the risk.
With mailbox access, an attacker can read messages, set forwarding rules, and wait for the right moment to request sensitive documents or change payment instructions. Because the mailbox is real, the requests appear authentic to recipients.
A firm-wide verification process for any change involving money or sensitive data, using an out-of-band method (calling a known phone number on file, not the number included in an email). Technology reduces compromise; process prevents the final step.
No. No provider can honestly guarantee that. What we can do is reduce the likelihood, limit the impact, and improve recovery speed and clarity through layered controls, safer access, and validated recovery steps.
It means you have controls that make ransomware harder to execute (strong identity protections and device standards), controls that limit spread (least privilege and segmentation), and a recovery plan that has been tested so your firm can restore priority systems without guessing.
They include useful features like version history and recycle bins, but they are not a complete backup strategy by themselves. A true backup plan includes separate recovery capability, retention, protection from tampering, and tested restores.
Immutable backups are stored so they cannot be altered or deleted for a defined period, even if an attacker gains admin access. This matters because ransomware often tries to delete backups first. Immutability improves recovery odds, but restore testing and a recovery plan are still required.
Change the password, revoke active sessions, confirm MFA is enabled, review forwarding rules and mailbox permissions, and check sign-in logs for unusual access. Then review recent messages for suspicious document requests, payment changes, or unusual sharing.
It depends on what systems are affected and how prepared the firm is. A realistic plan defines priorities (email, files, tax apps), sets recovery targets, and tests restore procedures. Any provider giving a universal recovery time without understanding your environment is guessing.
Microsoft 365 includes strong security capabilities, but results depend on configuration and consistency—especially MFA, conditional access, admin protections, device standards, and monitoring.
Focus on high-impact, low-friction habits: strong MFA, clear verification for sensitive changes, secure document sharing patterns, device standards, and tested recovery planning. The goal is fewer disruptions, not more steps.
Three things: what happened, what is impacted, and what we are doing next (with a realistic timeline). Clear answers protect client trust and reduce internal chaos.
