Antivirus still matters, but many successful attacks no longer begin with a malicious file. They begin with a valid username and password. Once an attacker can sign in as a real employee, the activity may look legitimate until money, data, or trust has already been lost.
The account is the new perimeter
Cloud email, shared documents, business applications, and remote access all depend on identity. That makes strong sign-in controls just as important as endpoint protection.
- Require multifactor authentication for every user.
- Block legacy authentication methods that bypass modern protections.
- Use separate administrator accounts and limit their everyday use.
- Review risky sign-ins, forwarding rules, and unfamiliar application permissions.
Make the secure choice the easy choice
Security works best when it is consistent and understandable. Clear sign-in prompts, password managers, phishing-resistant authentication, and short employee training sessions reduce both risk and frustration.
