🔥 One leaked API key = a client lost and your reputation damaged. Don’t be that developer. Stay protected with these battle-tested security tools — handpicked for freelancers.
🚨 Why Freelancers MUST Care About Cybersecurity in 2025
If you freelance, you’re a one-person army:
- Developer 🧑💻
- DevOps 🔧
- Product Manager 🧠
- Security Lead (whether you like it or not)
In 2025, attacks are smarter, sneakier, and way more automated.
You are the target — especially if you're:
- Deploying SaaS or APIs
- Working with sensitive data
- Using open-source dependencies
- Shipping code fast without automated scanning
🧨 One careless commit to GitHub and boom — your tokens are out there.
