Frequently Asked Questions

How often should I update my website security?

Security updates should be applied immediately when available. Perform comprehensive security audits quarterly, and vulnerability scans monthly. Critical patches should never wait more than 48 hours.

What's the most important security measure for small businesses?

Regular automated backups are the most critical. Even if everything else fails, backups let you recover quickly. Combine this with strong passwords, two-factor authentication, and keeping software updated.

How much should I budget for website security?

Budget 3-5% of your IT spending on security, or $200-500 monthly for small businesses. This covers security tools, monitoring, backups, and professional security audits. The cost of prevention is always less than recovery.
