If you need a network firewall with built-in vulnerability scanning, the first thing to clarify is what kind of scanning you need. Many next-generation firewalls (NGFWs) inspect traffic for known exploits and block attacks, but that is different from actively scanning your network devices, servers, and endpoints to find missing patches and known CVEs.
Here are the options I'd evaluate, depending on whether you want an all-in-one security appliance or a firewall paired with vulnerability management.
Recommended firewall solutions
1. Sophos Firewall
Best for small and midsize businesses
Sophos combines firewalling, intrusion prevention, malware protection, network threat detection, and security integrations. Its built-in network detection and response (NDR) helps identify suspicious activity and previously unknown threats.
Important caveat: NDR and exploit prevention aren't the same as a full network vulnerability scanner that inventories hosts and reports CVEs.
2. Fortinet FortiGate
Best for comprehensive network protection
FortiGate offers intrusion prevention, antivirus, application control, and threat protection. Higher-tier security bundles add capabilities such as IoT detection, vulnerability correlation, and attack-surface risk monitoring.
Important caveat: Confirm whether the exact model and subscription include active vulnerability scanning. Fortinet's own implementation guidance notes that endpoint vulnerability checks do not replace network vulnerability scanning.
3. Fortinet FortiWeb
Best if your priority is web application vulnerabilities
FortiWeb includes an active web vulnerability scanning feature that crawls web applications, checks for known application weaknesses, and produces scan reports. Scans can be scheduled or run manually.
Important caveat: This is a web application firewall (WAF), not a general-purpose perimeter firewall for scanning every device on your LAN.
Official scanning documentation
4. Cambium Networks NSE 3000
Best direct match for built-in LAN vulnerability assessment
The NSE 3000 explicitly advertises 24/7 vulnerability assessment for wired and wireless LAN devices, periodic CVE detection, risk scoring, and remediation recommendations. Vulnerability assessment is included with its Security Plus subscription.
This is one of the clearest matches to your stated requirement.
5. TXOne EdgeFire and EdgeOne
Best for industrial and OT environments
EdgeFire provides industrial firewall protection, while the EdgeOne management platform adds network-based vulnerability detection for operational technology assets. It identifies vulnerabilities through network traffic analysis, which is useful for devices that cannot run agents.
Quick comparison
Solution Active LAN vulnerability assessment Best fit Cambium NSE 3000 Yes; built-in, subscription-dependent Small business / LAN TXOne EdgeFire + EdgeOne Network-based OT vulnerability detection Industrial networks Sophos Firewall Primarily threat detection and prevention SMB security Fortinet FortiGate Security inspection and vulnerability correlation; verify scanning requirements SMB to enterprise Fortinet FortiWeb Yes, for web applications Public-facing websites My recommendation
- For a standard business network: Start with Cambium NSE 3000 if active CVE scanning of connected devices is a firm requirement.
- For an industrial network: Evaluate TXOne EdgeFire with EdgeOne.
- For broader enterprise security: Consider FortiGate, but verify whether you need an additional scanner to meet your requirements.
Before buying, confirm that the product can discover devices, identify vulnerabilities by CVE, produce remediation reports, and scan the specific assets you care about. These capabilities are not interchangeable with intrusion prevention.

Traditional firewalls focus on packet filtering and stateful inspection rather than active host vulnerability scanning, which is typically handled by dedicated assessment tools. However,
modern Next-Generation Firewalls (NGFWs)bridge this gap by offering integrated vulnerability assessment, continuous threat profiling, and deep packet inspection (DPI) that reacts dynamically to known CVEs.Leading enterprise options that combine network firewall protection with built-in or natively integrated vulnerability management include:
- Fortinet FortiGate (FortiOS) : Combines high-performance NGFW features with integrated vulnerability scanning, asset discovery, and compliance profiling. Through integration with FortiCNAPP and native security fabric telemetry, it continuously evaluates internal network elements and endpoints for misconfigurations and active exposures.
- Palo Alto Networks PA-Series (PAN-OS) : Features advanced threat intelligence and vulnerability assessment via subscriptions like WildFire and Vulnerability Protection. While it relies on continuous traffic inspection rather than active port-scanning of endpoints, it actively scans traffic for vulnerability exploits, maps behavior to specific CVEs, and dynamically blocks exploitation attempts.
- Cisco Secure Firewall (with Tenable Integration) : Cisco integrates vulnerability mapping directly into its management architecture. Utilizing native connectors (such as the Tenable connector for Cisco Security Cloud Control), it pulls host-to-CVE data directly into the firewall's object database, allowing administrators to automatically isolate vulnerable assets or apply targeted virtual patching.
- SonicWall NSa / TZ Series : Features a single-pass Reassembly-Free Deep Packet Inspection (RFDPI) engine that works alongside Capture ATP sandbox analysis to identify and remediate network vulnerabilities and active zero-day threats at the gateway level.
If you'd like to narrow this down, please let me know:
- Your deployment environment (on-premise data center, cloud/AWS/Azure, or branch office)
- Your approximate throughput or user count
- Whether you need an all-in-one appliance or an integration with an existing scanner (like Tenable or Qualys)

Examples of network firewall products that include native vulnerability scanning or vulnerability assessment capabilities are below. I’ve focused on products where vulnerability assessment/scanning is built into the firewall/UTM/NGFW platform rather than requiring only a separate third-party scanner.
Product Vendor Native vulnerability scanning capability Notes Cambium Networks NSE 3000 Next-Gen Firewall Cambium Networks Yes — LAN Vulnerability Assessment Performs periodic scans of wired and wireless devices, detects CVEs, and provides remediation recommendations. SecPoint UTM Firewall + Penetrator SecPoint Yes — integrated vulnerability scanning Combines UTM firewall functions with vulnerability scanning capabilities; the Penetrator scanner includes vulnerability signatures and network/device scanning. Fortinet FortiGate (with FortiGuard services) Fortinet Partial / security posture assessment features FortiGate provides vulnerability-related protections and integrations, though full authenticated vulnerability scanning is generally handled by Fortinet security products/services rather than the firewall alone. Cisco Secure Firewall Cisco Not a full native scanner; vulnerability intelligence integration Cisco Secure Firewall can consume vulnerability information from integrations such as Greenbone and correlate it with firewall visibility. Palo Alto Networks Next-Generation Firewall Palo Alto Networks Vulnerability protection (not asset vulnerability scanning) Provides built-in vulnerability protection profiles that block exploit attempts, but it is not the same as a traditional CVE scanner. Sophos Firewall / UTM platforms Sophos Limited (varies by platform/version) Sophos UTM/XG/XGS products historically included security assessment features, but dedicated vulnerability management is typically provided through Sophos Central ecosystem products. OPNsense / pfSense with add-ons Open-source firewall platforms Possible via integrated packages These platforms can run security tools, but vulnerability scanning is generally an add-on rather than a core firewall function. Important distinction
“Native vulnerability scanning” can mean two different things:
-
Active vulnerability scanner (Nessus/Qualys-style)
- Discovers hosts, fingerprints services, checks CVEs, and produces remediation reports.
- Example: Cambium NSE 3000’s LAN Vulnerability Assessment.
-
Firewall vulnerability protection / IPS
- Detects and blocks exploitation attempts against known vulnerabilities.
- Example: Palo Alto Networks vulnerability protection profiles.
If you need a true firewall appliance with an onboard CVE scanner, the list is much shorter; many enterprise NGFWs integrate with vulnerability scanners rather than embedding one directly.
I can also provide a vendor comparison matrix (Fortinet vs Palo Alto vs Cisco vs Sophos vs Check Point vs SonicWall) specifically for built-in vulnerability assessment features.

Traditional enterprise network firewalls and next-generation firewalls (NGFWs) do not feature native, active vulnerability scanning (such as credentialed or non-credentialed port-and-host vulnerability assessments typical of tools like Nessus or Qualys) . Instead, firewalls rely on Intrusion Prevention Systems (IPS) , deep packet inspection, and threat intelligence feeds to detect active exploit traffic passing through the data plane, rather than actively probing internal hosts for missing patches or software flaws.
Distinction: Vulnerability Scanning vs. Firewall IPS/Threat Detection
- Vulnerability Scanners (e.g., Nessus, Qualys): Actively send probe packets or log into endpoints to catalog software versions, missing patches, and misconfigurations.
- Next-Generation Firewalls (e.g., Cisco Firepower, SonicWall TZ Series): Inspect passing traffic for signatures of known vulnerabilities being exploited, but they generally depend on integrations with external vulnerability management platforms to map network context rather than running native active vulnerability audits.
Platforms Offering Contextual Vulnerability Integration
Product / Platform Native/Active Scanning Capability Integration Approach Cisco Secure Firewall / Firepower No active host vulnerability scanner built into the data plane. Integrates with Cisco Firepower Management Center to correlate vulnerability data from external scanners with IPS event data. Palo Alto Networks NGFW No native host scanner. Uses Expedition or external API connectors to ingest vulnerability assessment reports (e.g., Prisma Cloud/Third-party) for dynamic security policies. Fortinet FortiGate Contains FortiView/Asset Identity features, but no active vulnerability auditing engine. Integrates directly with FortiNAC and external scanners to isolate endpoints identified as vulnerable. If you are looking to integrate vulnerability management directly with your perimeter controls, let me know:
- Which firewall vendor you currently use
- Whether you prefer an API-based integration with an external scanner or a specific compliance framework (like PCI-DSS)
I can suggest the optimal architecture for matching your assessment tools to your network controls.
