Cybersecurity is no longer optional for businesses of any size — 43% of cyberattacks target small businesses. The right security stack depends on your threat model, but every organization needs identity management, endpoint protection, and network security at minimum.
Don't buy based on fear. Assess your actual risk profile first — a password manager and MFA will prevent more breaches than an expensive SIEM for most small businesses.
