Where Bolster.ai wins
Bolster is a real, well-funded security company with a deep platform. Their computer-vision ML for brand impersonation is the kind of thing that takes years of labeled data and a real research team to build — they'll spot a phishing site that's using your logo, your color palette, and your login form layout even when the URL is something obscure. Their proprietary takedown service is also genuine: they have established relationships with registrars, hosts, and CDN providers, and they get malicious domains pulled in hours instead of weeks. For a brand that's actively being impersonated, that's the difference between "customers got phished" and "customers tried to get phished and the site was already gone."
Add SOC 2 compliance, GDPR posture, dedicated customer success, real procurement and MSA paperwork, and the kind of internal threat-intel feeds that only a funded security company can maintain — Bolster earns its enterprise price tag. If you're evaluating them against PhishGuard for a Fortune 500 brand-protection program, pick Bolster. We mean that.
Where PhishGuard wins
PhishGuard exists because Bolster's pricing model locks out most of the people who actually need URL scanning: indie developers, SaaS engineering teams, IT departments at small companies, freelance IR analysts, and SMB owners. Bolster is sales-led — there's no public pricing page, no "sign up and use the API" flow, and the entry-level contract tends to start around twenty thousand dollars a year. That's the right answer for an enterprise. It's the wrong answer for someone shipping a side project that needs URL safety on user-submitted links.
PhishGuard is the inverse: flat $9/mo for 1k scans/day with a self-serve REST API, Slack and webhook delivery, a public Atom feed for SIEM ingest, and a free tier that doesn't require a credit card. Every verdict shows every source that contributed — URLhaus, Google Safe Browsing, VirusTotal, RDAP domain age, Claude AI page analysis — so you can audit the decision instead of trusting a black box. The free email scanner, header analyzer, and URL deobfuscator round out a working IR toolkit that costs nothing to start with.
Who each is for
You're a Fortune 1000 security team. You need takedowns. You need CV brand-impersonation ML. You need a SOC 2'd vendor with a procurement-friendly contract and a CSM on speed dial. You have budget for a real platform. Go with Bolster. Honestly.
You want a self-serve REST API for $9/month. You want to see why a URL was flagged. You want webhook delivery into Slack or Splunk without a sales call. You want to add URL safety to your own app without committing to an enterprise contract.
Bolster is a brand-protection platform. PhishGuard is a phishing scanner. The overlap is real but partial. If your budget allows Bolster, you should probably buy Bolster. If it doesn't, PhishGuard covers 70% of the same daily workflows for less than 1% of the cost.
