VigilDNS as a Bolster alternative for lookalike domain monitoring

Bolster (bolster.ai) is an AI-powered phishing and scam protection platform best known for fast automated takedowns, and it covers domains, social media, app stores, and the dark web. VigilDNS focuses entirely on lookalike domains and the websites on them, with published pricing from $79 per month. Here is an honest comparison, including where Bolster is clearly the stronger choice.

What Bolster offers

Bolster detects phishing and scam sites with AI and then removes them: automated takedown is the headline feature. The company says 75% of its takedowns happen within minutes through automated connections with registrars and hosting providers, that 95% need no manual intervention, and that providers without those connections receive evidence-based takedown emails. Its products cover domain monitoring and takedowns, social media, app stores, and dark web monitoring, so a security team can see impersonation across channels in one place. Bolster also runs CheckPhish, a genuinely useful free URL scanner that also offers typosquat monitoring for a single domain. Pricing for the full platform is not published; Bolster directs buyers to its sales team for pricing and packages.

What VigilDNS offers

VigilDNS watches the domain layer continuously, rescanning every 24 or 12 hours by plan. A permutation engine generates lookalikes of your domains using 13 techniques, including homoglyphs, swaps, omissions, bitsquatting, and TLD swaps, and monitors which are registered and live. Each hit comes with full DNS records (A, AAAA, MX, NS, CNAME, SPF, DMARC, DKIM, TXT) and a change history, a 0-100 risk score, and, on the top risks, an AI verdict on intent (phishing, malware, counterfeit, parking, redirect, or legitimate) with confidence and a written rationale. Certificate history and live TLS are kept for every lookalike (background in our guide to Certificate Transparency monitoring), page screenshots are compared side by side against your real site for clone detection, and campaign detection clusters domains operated by the same actor. Dormant threat detection and flags for lookalikes with a working mail server surface infrastructure that is staged but not yet in use. ASN and geo attribution, RDAP registration data, email alerts when a scan finds newly registered lookalikes, tenants with member roles, CSV and JSON exports, and takedown-ready drafts you send yourself round it out.

Bolster vs VigilDNS at a glance

Both products take phishing infrastructure seriously. The structural differences are takedown automation, channel breadth, and how you buy.

Bolster details were checked against its public pages on 2026-09-28. "Not published" means those pages do not document the capability; ask Bolster for current details.

Pricing: sales-quoted packages vs published plans

Bolster sells its platform through sales; no prices are published. VigilDNS publishes everything: Starter at $79/mo (5 domains, 3 seats, scans every 24 hours), Team at $199/mo (20 domains, 10 seats, 12-hour cadence), Business at $899/mo (100 domains, 25 seats, 12-hour cadence), and a quote-based Enterprise tier for larger portfolios. Annual billing gives 2 months free, and every plan includes the full detection feature set.

When Bolster is the better fit

If takedown speed is your priority, Bolster is the better product for you, full stop. Automated removal of confirmed phishing sites, which Bolster reports often happens within minutes, is something VigilDNS deliberately does not do; we prepare the drafts and evidence, and you send the report. Bolster is also the right call if you need impersonation coverage across social media, app stores, and the dark web in one platform, and you have the budget and appetite for an enterprise sales motion. Teams already happy with CheckPhish who want the full multi-channel platform behind it have a natural upgrade path with Bolster.

When VigilDNS is the better fit

If your need is specifically lookalike domains, the kind of problem described in someone registered a lookalike of my domain, VigilDNS covers that slice deeply: continuous permutation scanning, DNS change history, certificate history, screenshot clone comparison, and actor-level campaign clustering, all at a price point that does not require a procurement cycle. It suits small security and IT teams, MSPs, and founders who want deep domain intelligence without an enterprise contract.

Frequently asked questions

Is CheckPhish the same as Bolster?

CheckPhish is Bolster's free URL scanner, which also offers typosquat monitoring for a single domain. It is a small subset of the paid Bolster platform, which adds multi-channel coverage and automated takedowns. VigilDNS similarly offers a free scan at the typosquat checker, with continuous monitoring on paid plans.

Does Bolster publish pricing?

No. Bolster directs buyers to its sales team for pricing and packages. VigilDNS publishes all plans at /pricing, starting at $79/mo.

Does VigilDNS take down phishing sites?

No. VigilDNS compiles the evidence (screenshots, registration data, and DNS, hosting, and mail details) into takedown-ready drafts grouped by the abuse address that handles each lookalike, and you send them to registrars and hosting providers yourself. If you want automated takedowns handled for you, Bolster is built for exactly that.

What does VigilDNS detect that a one-off scan misses?

Change over time: a lookalike gaining a working mail server, dormant domains waking up, fresh certificates appearing, and pages turning into clones of yours. Rescans every 24 or 12 hours by plan catch the move from parked to active, with email alerts for newly registered lookalikes and in-app alerts for DNS changes and flagged AI verdicts.

Try it on your own brand first: the free typosquat checker shows registered lookalikes with no signup, and pricing is published for every plan, with self-serve signup and no sales call.
