Freelance web security and performance expert

Work with a developer who cleans up and locks the door behind them

Cleaning a hacked site isn't enough: you need to find how the attack got in. On ComeUp, freelance web security and performance experts explain their methods and show their client reviews. Ask for a report afterwards: what was found, what was fixed and what still needs watching.
