Python

If you handle suspicious files — malware samples, email attachments, downloads from sketchy URLs — you’ve done the dance: hash the file, open VirusTotal, paste the hash, wait, repeat. It’s slow, manual, and burns your attention on process instead of analysis.

Security headers are the cheapest defense you can deploy. They cost nothing, take minutes to configure, and block entire classes of attacks — XSS, clickjacking, MIME sniffing, SSL stripping. Yet most sites get them wrong, or don’t set them at all.
