The Risks of Phishing

The consequences of falling victim to a phishing attack can be severe, resulting in substantial financial loss and reputational damage.

4. Verify Sources: Instruct individuals to independently verify the identity of anyone requesting sensitive information, whether via email, phone, or other channels. If in doubt, contact the organization directly using known contact information.
   
   
5. Stay Updated: Keep software, systems, and security protocols updated to protect against vulnerabilities that attackers could exploit. Staying informed about the latest phishing tactics can help organizations adapt their defenses.
