Vulnerability Manager Product Information
Learn more about GeoTrust Vulnerability Manager's capabilities.
Here's a closer look at Vulnerability Manager's features and requirements.
- 375,000+ vulnerability checks covering operating systems, installed software, and configurations
- Two scan types: an external scan via the asset’s public IP address, and an internal scan run by an agent installed on the asset
- External scans run automatically every day
- Internal scans run automatically at least once a day; the agent limits its CPU use so it won't slow your server.
- On-demand scans can be triggered manually at any time
- Assets are added by IPv4 address: a public address is required for external scans, and a public or private address is accepted for internal (agent-based) scans
- Internal agent supports Windows and Windows Server, most Linux distributions common Unix systems including BSD, AIX and Solaris, and macOS
- Processor support: x86-64 (Intel and AMD), ARM64, PowerPC and SPARC.
- External scanning requires no agent and is OS-independent
- Internal agent requirements: administrator or root access to install, plus outbound HTTPS on port 443
- No inbound firewall rules required — agent communication is outbound only over an encrypted connection
- Five severity levels: Critical, High, Medium, Low, and Very Low
- Every finding is labeled confirmed or potential
- Remediation guidance with every finding: 96% of all checks have a known patch or fix
- AI Remediation Advice provides remediation steps and instructions specific to your OS
- Alerts are sent when new high/critical vulnerabilities are detected, plus a monthly report
- Notification methods supported: Email, Slack, Microsoft Teams, Discord, Google Chat, Zapier, n8n, Power Automate, Make, & webhooks
- Unlimited notification recipients: send alerts to as many people and channels as you need.
- Export your current results as a CSV file or a PDF
Vulnerability Manager offers two scan types, external and internal. Here’s a guide to help you choose the best scan type for your specific use case. For detailed setup requirements for any of these scan types, see the knowledgebase.
Scan a server with a public IPv4 address (e.g. web server, mail server, database server, etc.). We recommend running both internal and external scans for comprehensive results, or you can choose to run only one type if you prefer.
A cloud virtual machine/VPS hosted on a provider such as AWS, Microsoft Azure or Google Cloud, or a virtual machine on your own hypervisor or private cloud. It may have a public IPv4 address, or it may only be reachable on a private network.
Any server that is not reachable from the internet such as a file server, application server, office server, private dev server, etc. Since it uses a private IP address, there is nothing for an external scan to connect to.
A desktop, laptop or other workstation used by an employee, whether it sits in the office or connects from home or another location. Workstations are rarely reachable from the internet; instead the internal agent reports from the device as long as it can connect outbound.
A public load balancer in front of two or more backend servers. We recommend running an internal scan on each backend server, then scanning the load balancer's public IP as a separate external asset.
A load balancer, firewall, router or similar device with its own IP address. Run external scans if it has a public IP address and internal scans if you have root access to install the agent (e.g. a device that runs a supported Linux distro).
A website hosted with a shared hosting provider where you can manage your website but cannot install software on the underlying server. You can technically run external scans but be aware that the entire server will be scanned (including other websites). Check your hosting provider’s policy on vulnerability scanning before you start.
A Linux server that runs Docker or Kubernetes workloads, such as a self-managed cluster node or a fixed-size node group. The internal agent scans the node's operating system and host-level software, not container images. Nodes must run a supported Linux distribution. Autoscaling node groups, container-optimized OSes (Bottlerocket, Container-Optimized OS) and serverless options (Fargate, GKE Autopilot) aren't a good fit.
A vulnerability scanner checks a server or other device against a catalog of security weaknesses that are already known and documented and tells you which of them apply to you. Vulnerability Manager runs more than 375,000 of those checks against the operating system, the software installed, the open ports, and the way it is all configured — then tells you how to fix what it finds.
While there is some overlap, these are separate tools. Vulnerability Manager checks the server your website runs on: the operating system, the software installed on it, the open ports, and the configuration, all against vulnerabilities that are already known and cataloged. A website security scanner tests your site itself, including your own code, forms, and logins, for flaws like SQL injection and cross-site scripting. Both are useful, and they answer different questions.
External scanning needs nothing installed and shows you what someone outside can reach. Internal scanning uses a small agent on the asset and sees considerably more, because most known vulnerabilities are not easily visible (i.e. without running an exploit against your server) from outside. (Note that "not visible from outside" is not the same as "not a problem" — a scanner asks polite questions, and an attacker does not.) Running both gives you the fullest picture.
Anything you run that has a public-facing IP address, or that you can install the agent on. That covers Windows and Linux servers, Unix systems, macOS machines, virtual machines, cloud instances, load balancers, firewalls, and devices on a private network. You add each asset yourself by entering its IP address—Vulnerability Manager assesses the machines you specify rather than searching your network for devices you have not told it about.
Findings include vulnerability severity ratings, whether it is confirmed or potential, relevant CVE references, and remediation guidance. You’ll see the recommended upgrade, links to the vendor’s patch, and any available workarounds. AI Remediation Advice goes further and gives the specific steps and commands for that server, along with how to check the fix worked.
Your external scan starts shortly after your subscription is set up, and your internal scan starts once the agent is installed and connected. Results appear in your dashboard once a scan completes. The first internal results can take a full cycle to come through (depending on your server’s available resources and other factors), so if it has been less than 24 hours, give the agent a little more time.
One subscription covers one server, so fifty servers mean fifty subscriptions. The price per server falls as you add more, from $12.00 a month down to $3.50 a month at a hundred assets or more, with discounts applied automatically when the assets are in the same account. See the pricing page for all tiers.
No contracts and no commitments. Pay monthly or annually, add or remove servers anytime, and get a lower per-server price as you scale. Cancel anytime.
No, and that is a deliberate choice rather than a missing feature. Customers told us clearly that they did not want a security product patching production servers on its own schedule. Vulnerability Manager finds the problem, tells you exactly how to fix it, and leaves the timing of the change with you.
96% of the checks we run have a known patch or fix behind them. Where the vendor has not released one, the report tells you so plainly instead of leaving you guessing, and AI Remediation Advice can often suggest a way to work around the issue or reduce the risk until a patch exists.
Historical data is used to show you when a vulnerability was first found, whether it has been fixed, etc. Your dashboard and your reports show your current position — the most recent result for each finding — rather than a record of every scan we have run. You can export your current results as a CSV file or a PDF whenever you like and keep your own copies.
Vulnerability Manager is not a compliance certification product, and it does not issue compliance reports. However, it does the thing many of those requirements are actually asking for: it finds and documents the known vulnerabilities on the assets you add, on a schedule, and lets you export your current results as a PDF or a CSV to send to an insurer, an auditor or a client. If your compliance framework requires documented evidence of general vulnerability scans run on your systems, Vulnerability Manager can help you.
