Helping CPA Firms Stay Secure, Compliant & Productive Since 2011

Email Protection Built Around How Attackers Target CPA Firms

Most email security tools aren’t built for the risks accounting firms face. InnerPC configures your defenses around the phishing and impersonation tactics used to target client financial data, especially during tax season.


From spoofed-invoice detection to attachment scanning, nothing is generic. Your firm gets email protection shaped entirely around how accountants actually work.
