Why choose EZMonitor?
SSL monitoring prevents costly breaches and outages. EZMonitor finds every certificate issued for your organization, then tells you which ones are about to hurt.
Gain full visibility into your SSL certs
EZMonitor's hosted architecture gives you full visibility into all your SSL certificates in one dashboard, so your team can start monitoring SSL health in minutes. Receive alerts by email, through a SIEM integration, or by calling our APIs.
Prevent costly outages
More than 80% of organizations have reported a certificate related outage in the past two years. EZMonitor finds every certificate and alerts you before one expires.
Remediate vulnerable misconfigurations
Monitor your domains for known SSL misconfigurations that could open the door for an attacker. During EZMonitor's first month, over 30,000 cloud misconfigurations were detected.
Comply with CT Log requirements
The Department of Homeland Security mandates that all federal agencies use a Certificate Transparency monitor like EZMonitor to identify unauthorized SSL certificate issuance, ensuring potentially fraudulent certificates are detected.
Detect phishing attacks quickly
With phishing attacks tripling over the past year, you need to stop an attack before it becomes a costly breach. EZMonitor's smart alerting surfaces domains and subdomains attackers are using to impersonate your company.
Full visibility into shadow PKI
Public and private network scanning gives you a complete SSL certificate report card. That includes the shadow IT certificate authorities engineers stand up when they need a certificate and skip the approved private CA.
Start monitoring in 3 easy steps
Nothing to deploy for public monitoring, and no certificate inventory to build first.
Add your domains
Tell EZMonitor which domains are yours. It immediately begins scanning Certificate Transparency logs for every certificate issued against them, including ones you didn't know about.
Review your SSL health
The EZMonitor dashboard provides a report card for your certificate estate: what is expiring, what was renewed but never installed, what was issued by an unexpected CA, and what looks like impersonation.
Get alerted before it breaks
Route alerts to email, to your SIEM, or through our APIs, with step by step remediation guidance so the person who picks it up knows what to do.
Where teams use EZMonitor
One scan surface covers unauthorized issuance, expiry, impersonation, and the certificates inside your own network. Explore the one closest to your problem.
Find certificates nobody told you about
Unauthorized issuance ranges from a developer skipping your approved process to an attacker compromising a CA and issuing a rogue certificate on your behalf. Certificate Transparency logs make both visible.
-
Every publicly trusted certificate is logged before a browser will trust it, so nothing issued for your domain stays hidden
-
Alerts on certificates from an unexpected CA, the signal that someone went around your process
-
Meets the DHS monitoring mandate for federal agencies identifying unauthorized issuance
Stop the outage before the certificate expires
Over 80% of companies have reported a certificate related outage, including high profile ones. The failure is rarely that nobody renewed; it is that nobody knew which certificate was about to lapse.
-
Alerts on certificates near expiry that have not been renewed yet
-
Catches the renewed-but-not-installed case by scanning your public endpoints for what is actually being served
-
Gartner puts the average outage at $300,000 per hour, which one caught certificate pays for many times over
Catch impersonation while it is still being set up
Attackers register a subdomain containing your domain, such as your_domain.com.attackers_domain.com, so the address looks legitimate at a glance. Getting a certificate for it puts them in the logs.
-
Alerts on certificates for subdomains containing your domain, the classic phishing setup
-
Finds dangling DNS entries pointing at cloud resources you no longer own, which is how subdomain takeover works
-
Over 30,000 vulnerable Azure domains were found in EZMonitor's first month of operation
See the private certificates too
Certificate Transparency only covers publicly trusted certificates. EZMonitor's internal network scan closes the gap by running an agent inside your environment on the Enterprise plan.
-
Downloads certificates issued by your AD CS CA and checks them for errors that could cause an outage
-
Active Directory DNS lookup finds the domains you host so you do not have to maintain the list by hand
-
Scans every discovered domain and alerts on any SSL issue found on the network

Frequently asked questions
Every publicly trusted certificate must be registered in Certificate Transparency logs by the certificate authority before a browser will trust it. EZMonitor scans and indexes those logs, so it finds certificates issued for your organization even when they were issued without your knowledge.
Yes. That is the point of monitoring the logs. Unauthorized issuance ranges from a developer skipping your approved process and buying a certificate elsewhere, to an attacker compromising a certificate authority and issuing a rogue certificate on your behalf. EZMonitor alerts on both.
Yes. EZMonitor alerts on certificates approaching their expiration date that have not been renewed, and it also scans your publicly available endpoints to catch the case where a certificate was renewed but never installed.
Yes. EZMonitor alerts you when a certificate is issued for a subdomain containing your domain, which is a common way attackers make a phishing site look legitimate. It also scans your subdomains and alerts on dangling DNS entries pointing at cloud resources, which is how subdomain takeover happens.
Yes, on the Enterprise plan. Internal network scanning runs through an agent you install on a Windows machine, which can download certificates from your AD CS certificate authority, use Active Directory DNS lookup to discover domains, and scan those domains for SSL issues.
The Department of Homeland Security mandates that federal agencies use a Certificate Transparency monitor to identify unauthorized certificate issuance. EZMonitor is that kind of monitor, so it can be used to meet the requirement.
EZMonitor starts at $20 per month for Startup, which monitors up to 10 subdomains. Basic is $200 per month and covers all your domains and subdomains. Enterprise is $2,500 per month and adds internal network scanning, a SIEM connection, and 24/7 support.
