Body Paragraphs: What to Highlight

Technical Expertise

Demonstrate your command of key skills like Firewall management (Palo Alto/Fortinet), VPN configuration, IDS/IPS. Use specific examples rather than vague claims. Hiring managers for network security engineer roles want evidence, not assertions.

Where you have real numbers, use them. Instead of “improved performance”, say by how much, but never invent a figure.

Soft Skills in Action

I would love to discuss this opportunity in more detail. Please feel free to reach me at [email or phone]. Thank you for your time.”
