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-domain and phishing-infrastructure monitoring, 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: its automated takedown technology is the headline feature, with the company reporting that a large share of confirmed threats come down within minutes through provider APIs. The platform is sold in modules covering web and domains, social media, app stores, and dark web monitoring, so a security team can see impersonation across channels in one place. Bolster also runs CheckPhish (checkphish.ai), a genuinely useful free URL and website scanner that exposes a small subset of the platform's capability. Pricing for the full platform is not published; it is an annual subscription per module, sold through an enterprise sales process.
What VigilDNS offers
VigilDNS watches the domain layer continuously. A permutation engine generates lookalikes of your domains using 11 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 an AI verdict on intent (phishing, malware, parking, redirect, or legitimate) with confidence and a written rationale. Live Certificate Transparency log monitoring catches new certificates as they are issued, 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 MX-based mail-capability checks flag infrastructure that is staged but not yet weaponized. ASN and geo attribution, RDAP registration data, real-time email alerts, team workspaces, and CSV export round it out.

Pricing: per-module quotes vs published plans
Bolster sells annual module subscriptions 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 with a 4-hour cadence. 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 within minutes is something VigilDNS deliberately does not do; we hand you the evidence and you file 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, CT log hits, screenshot clone comparison, and actor-level campaign clustering, all at a price point that does not require a procurement cycle. It suits small security teams, MSPs, agencies, and founders who want enterprise-grade domain intelligence without an enterprise contract.

Frequently asked questions
Is CheckPhish the same as Bolster?
CheckPhish is Bolster's free URL and site scanner. It is a small subset of the paid Bolster platform, which adds continuous monitoring, multi-channel coverage, and automated takedowns. VigilDNS similarly offers a free instant scan at the typosquat checker, with continuous monitoring on paid plans.
Does Bolster publish pricing?
No. Bolster's platform is priced per module on annual subscriptions through its sales team. VigilDNS publishes all plans at /pricing, starting at $79/mo.
Does VigilDNS take down phishing sites?
No. VigilDNS compiles the evidence, screenshots, DNS and certificate history, and registration data, so you can file abuse reports with 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: DNS records flipping to mail-capable, dormant domains waking up, new certificates appearing in CT logs, and pages turning into clones of yours. Continuous scans plus real-time alerts catch the transition from parked to weaponized.
Try it on your own brand first: the free typosquat checker shows registered lookalikes instantly, and pricing is published for every plan, with self-serve signup and no sales call.
