Hover or tap a step title to expand it and see full details

Step 01

Scoping & Rules of Engagement
Before testing begins, we define your network attack surface and business-critical assets. We also identify the threat actors most likely to target your organization.
- Stakeholder discussion to confirm scope & rules of engagement
- Identify in-scope IP ranges, domains & network segments
- Align the testing approach with applicable security and compliance requirements
Step 02

Network Discovery & Enumeration
Next, we map live hosts, exposed services and network architecture. This creates a clear view of the real network attack surface.
- Host, port & service enumeration across the network
- Identify exposed devices, protocols & entry points
- Fingerprint OS, firmware & software versions in use
Step 03

Vulnerability Assessment
During this stage, authenticated and unauthenticated scans identify potential weaknesses. We then manually verify the results to remove false positives and identify exploitable issues.
- Automated scanning across network, wireless & VPN layers
- Manual triage to eliminate false positives
- Firewall & device configuration review against CIS benchmarks
Step 04

Controlled Exploitation & Penetration Testing
Once significant vulnerabilities are validated, our consultants safely test their exploitability. This helps demonstrate real business impact rather than relying only on theoretical risk scores.
- Controlled exploitation with proof-of-concept evidence
- Lateral movement & privilege escalation testing
- Assess potential for data exfiltration & service disruption
Step 05

Risk Prioritization & Reporting
At this stage, each finding is assessed using CVSS severity and business impact. The results are then converted into a clear remediation roadmap that your team can act on.
- CVSS-based severity scoring for every finding
- Executive summary & detailed technical report
- Step-by-step remediation guidance per vulnerability
Step 06

Remediation Validation & Reassessment
After remediation, we retest the identified vulnerabilities. This confirms whether the fixes work and provides documented closure evidence for the engagement.
- Reassessment of identified vulnerabilities after remediation, based on the agreed engagement scope
- Updated report & closure confirmation
- Engagement completion and retest documentation

Network Security & VAPT FAQs

Frequently Asked Questions About Network Security & VAPT

Find answers to common questions about Network Security Assessment,
Network Vulnerability Assessment, Network Penetration Testing and
Network VAPT services.

What is Network VAPT and what does it include?

Network VAPT is a security assessment that combines Network
Vulnerability Assessment and controlled Network Penetration
Testing to identify, validate and prioritize security weaknesses
across an organization’s approved network infrastructure.
Depending on scope, testing can cover internet-facing and
internal systems, servers, network devices, firewalls, VPNs,
wireless networks, exposed services, configurations and
segmentation. Significant vulnerabilities can be manually
validated to determine exploitability, attack paths and potential
business impact.

What is the difference between Network Vulnerability Assessment and Network Penetration Testing?

Network Vulnerability Assessment identifies and prioritizes
security weaknesses across approved network assets, services,
systems and configurations. Network Penetration Testing goes
further by safely attempting to exploit selected vulnerabilities
to validate whether they are actually exploitable and determine
potential attack paths and impact. Network VAPT combines both
approaches for broader network security validation.

What is the difference between Internal and External Network VAPT?

External Network VAPT evaluates internet-facing systems,
public IP addresses, exposed services, perimeter devices and
remote-access infrastructure from an external attacker
perspective. Internal Network VAPT assesses approved internal
systems, servers, network segments, services, trust relationships
and access controls to identify weaknesses that could enable
unauthorized access, privilege escalation or lateral movement.
Organizations may perform both assessments for comprehensive
network security coverage.

What does a Network Security Assessment test?

A Network Security Assessment can evaluate network architecture,
exposed services, operating systems, network devices, firewalls,
routers, switches, VPNs, wireless networks, authentication,
access controls, security configurations, segmentation and
vulnerability exposure. The exact scope is defined according to
the organization’s infrastructure, objectives and approved
testing requirements.

How does a Network VAPT assessment identify and prioritize vulnerabilities?

Network VAPT uses network discovery, service enumeration,
vulnerability assessment, configuration analysis and controlled
penetration testing to identify security weaknesses. Findings are
evaluated based on factors such as severity, exploitability,
affected assets, exposure, attack paths and potential business
impact. This helps security teams prioritize remediation based on
actual risk rather than vulnerability counts alone.

How much does Network VAPT cost?

Network VAPT pricing depends on the assessment scope, number of
IP addresses and assets, network segments, internal and external
coverage, infrastructure complexity, testing depth, wireless or
VPN testing requirements, reporting needs and retesting. A
tailored quotation based on the approved scope provides a more
accurate estimate than a fixed per-asset price.

What deliverables are provided after Network VAPT?

Network VAPT deliverables typically include an executive
security summary, detailed vulnerability findings, severity and
risk ratings, affected assets, technical evidence and validated
proof-of-concept details where applicable. Reports also include
remediation recommendations and, when included in scope,
remediation validation or retesting results to help organizations
reduce network security risk.
