Defending Against Phishing Attacks: A Guide for Florida Businesses

Phishing attacks account for over 80% of reported security incidents among Florida small and mid-size businesses. Attackers send convincing emails impersonating banks, vendors, the IRS, or even your CEO — tricking employees into revealing credentials or transferring money. With South Florida's diverse business community, attackers often craft phishing emails in English, Spanish, and Portuguese to target employees across Miami's multilingual workforce.

Modern Phishing: Beyond the Obvious Scam

Today's phishing attacks are sophisticated. Spear phishing targets specific individuals using personal information gathered from LinkedIn and other sources. Business Email Compromise (BEC) attacks impersonate executives to authorize fraudulent wire transfers — Miami businesses lost millions to BEC in 2024 alone. Vishing (voice phishing) involves phone calls from fake IT support or bank fraud departments. And smishing uses text messages to steal credentials or install malware.

Technical Controls to Block Phishing

Effective anti-phishing requires: email authentication protocols (SPF, DKIM, DMARC) configured correctly on your domain, advanced email filtering that uses AI to detect suspicious content and sender patterns, multi-factor authentication so stolen passwords alone can't grant access, DNS filtering to block known phishing sites, and endpoint protection that can detect and block malicious attachments and links before they execute.
