Network Vulnerability Assessment Services

What our network vulnerability assessment covers

Using Tenable Nessus Professional's plugin library — updated with new CVE and configuration checks continuously — we scan internal and external network ranges to build a prioritised, CVSS-scored inventory of exploitable weaknesses. Credentialed scans authenticate into hosts for deep visibility into missing patches and local misconfigurations; uncredentialed (external) scans show exactly what an unauthenticated attacker on the internet would see.

• External perimeter scanning — Internet-facing IPs, exposed services, and open ports as seen by an outside attacker.
• Internal network scanning — Servers, workstations, and network devices scanned from inside your perimeter for lateral-movement risk.
• Credentialed patch & CVE detection — Authenticated scans surface missing OS and application patches down to the specific CVE.
• Misconfiguration detection — Weak protocols, default credentials, unnecessary open services, and insecure device settings.
• Malware & ransomware indicator scanning — Detection of known malware signatures and indicators of compromise on scanned hosts.
• Prioritised remediation — Findings ranked by CVSS v3 score and exploitability, so your team fixes what matters most first.

Why choose eNeoteric for network vulnerability assessment

• Continuous or point-in-time — Run as a one-time baseline, or on a monthly/quarterly recurring cadence to catch new CVEs as they're disclosed.
• Human-reviewed findings — Every Nessus finding is reviewed by our engineers to strip out false positives before it reaches your report.
• CERT-In empanelled — Reports built to the evidence standard Indian regulators and auditors expect.
• Clear escalation path — Critical findings that warrant manual exploitation are flagged for a follow-up penetration test.
• Compliance-ready — Scan cadence and reporting formatted to support ISO 27001, SOC 2, and RBI/SEBI/IRDAI audit requirements.

Frequently asked questions

What's the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment (VA) uses a scanner like Nessus to identify known CVEs and misconfigurations across your network — it's fast, broad, and repeatable. A penetration test goes further: a human tester actively exploits confirmed vulnerabilities to chain them together and demonstrate real business impact. Most compliance frameworks require both — regular VA scans plus at least an annual pentest.

What is credentialed vs uncredentialed scanning?

An uncredentialed scan probes hosts without login access — it shows what an outside attacker sees, but misses many local vulnerabilities. A credentialed scan authenticates into each host (via SSH, WinRM, or a similar protocol) and can enumerate missing patches, installed software versions, and local misconfigurations far more accurately. We recommend credentialed scanning wherever possible for internal assets.

How often should we run network vulnerability scans?

Monthly or quarterly for most organisations, with additional ad-hoc scans after major infrastructure changes. High-risk environments (BFSI, healthcare, critical infrastructure) often scan weekly or continuously alongside patch management cycles.

Does this cover cloud infrastructure as well as on-premise?

This service covers on-premise servers, endpoints, and network devices. For AWS, Azure, and GCP workloads, see our dedicated cloud vulnerability assessment service, which uses Nessus's cloud-aware scanning alongside cloud configuration review.

From findings to remediation

An assessment tells you what is exposed. Closing those findings on network infrastructure — firmware upgrades, configuration hardening, replacing unsupported hardware — is separate work, and ENCSE delivers it.
