HubSpot forms are under attack by bots–how do you protect CRM data?

Question

We manage $50–100K/month in Google Ads, and this year we’re seeing sophisticated bots hitting HubSpot forms. They’re bypassing visual reCAPTCHA, dynamically filling form fields, and flooding our CRM with fake submissions. Behavior-based pre-submit checks (patterns, devices, IPs, timing) helped reduce spam. For high-traffic campaigns, real-time bot filtering tools like Clickfortify were especially effective. Has anyone else run into this? What solutions have worked for you to block advanced bot traffic without disrupting real users?

HackerNews · Accepted Answer

To protect CRM data from sophisticated bots, consider implementing a multi-layered approach. Start by enhancing form security with techniques like honeypot fields, which are invisible to humans but attractive to bots. Additionally, utilize advanced CAPTCHA solutions that incorporate behavioral analysis, such as Google's reCAPTCHA v3, which scores user interactions to determine likelihood of being a bot. For real-time protection, integrate bot management tools that analyze traffic patterns, device fingerprints, and IP reputation to identify and block malicious activity.
