External Attack Surface
Identify reachable hosts, ports, services, exposed management interfaces and security weaknesses visible from the internet.
Testing & Assurance
Identify Weaknesses Across Your External and Internal Infrastructure
Cybersentinels Consulting assesses networks and infrastructure for vulnerabilities, insecure services, weak configurations, excessive exposure and attack paths that may affect critical systems and information.
Our external and internal VAPT services help organizations understand how their infrastructure appears to an attacker and where controls should be strengthened.
Evaluate Exposure from Outside and Within the Network
Internet-facing infrastructure may expose services, devices and administrative interfaces to external attackers. Internal infrastructure can introduce additional risks through weak segmentation, excessive trust, legacy protocols and insecure configurations.
We assess the approved infrastructure using discovery, vulnerability identification, configuration analysis and controlled validation. External testing is commonly performed with black-box access, while internal testing may use grey-box access from an agreed network position.
The engagement is designed to identify priority weaknesses without disrupting business operations. Intrusive techniques, denial-of-service activity and high-risk validation require explicit authorization.
Infrastructure Security Areas We Assess
Depending on scope, assessment may cover:
Internal Network
Assess hosts, services, devices and trust relationships from an authorized internal position.
Vulnerable and Legacy Services
Identify outdated software, weak protocols, known vulnerabilities and unsupported components.
Security Configuration
Review insecure defaults, unnecessary services, weak encryption, anonymous access and other configuration risks.
Segmentation and Trust
Evaluate whether network boundaries and access restrictions reduce movement between user, server and critical environments.
Administrative Exposure
Assess interfaces and services used to manage infrastructure for excessive access or weak protection.
Identity and Credential Risk
Evaluate relevant authentication weaknesses, default credentials or password-related exposures within the approved rules.
Attack-Path Analysis
Determine whether weaknesses can be combined to increase access or affect higher-value systems.
Our Network and Infrastructure VAPT Process
- 01
Scope and Safety Planning
Confirm IP ranges, locations, testing positions, exclusions, critical systems, windows and escalation contacts.
- 02
Asset and Service Discovery
Identify live hosts, ports, protocols, technologies and accessible administrative interfaces.
- 03
Vulnerability Identification
Assess discovered services and systems for known weaknesses and security misconfiguration.
- 04
Manual Validation
Review relevant results, reduce false positives and validate exposure within agreed safety constraints.
- 05
Segmentation and Attack-Path Review
Evaluate network trust and potential movement where included and authorized.
- 06
Risk Analysis and Reporting
Prioritize findings using technical severity, exposure, asset importance and business impact.
- 07
Walkthrough and Retesting
Discuss remediation with stakeholders and verify corrected findings where included.

- Testing source or VPN arrangements
- Critical systems and explicit exclusions
- Cloud or on-premises ownership
- Firewall allowlisting requirements
- Testing windows and emergency contacts
- Retest expectations
When to Conduct Infrastructure VAPT
- As part of an annual or recurring assessment program
- Before or after significant infrastructure changes
- Following cloud migration or network redesign
- Before audits, certifications or customer reviews
- After introducing remote access or new internet-facing services
- Following acquisition, consolidation or location expansion
- When suspected exposure or unauthorized access requires validation
Why Cybersentinels for Infrastructure VAPT?
Infrastructure VAPT reflects the approved IP ranges, testing position, network accessibility and assessment period. Systems not reachable or not included in the confirmed scope are not covered.
- External and internal assessment options
- Black-box and grey-box testing approaches
- Validation beyond scanner output
- Focus on segmentation and attack paths where included
- Clear asset-level evidence and remediation guidance
- Reporting for management and infrastructure teams
- Retesting and closure support where included
Frequently Asked Questions
What is the difference between external and internal VAPT?
External VAPT assesses internet-facing exposure from outside the organization. Internal VAPT assesses systems and trust relationships from an authorized internal network position. Many organizations use both for a broader view.
Will testing disrupt our network?
Testing is planned to minimize operational impact. Critical systems, restricted techniques, maintenance windows and escalation contacts are agreed before testing. Denial-of-service testing is excluded unless specifically authorized.
Do you need credentials?
External black-box testing may not require credentials. Internal grey-box testing may use network access or agreed credentials to assess authenticated exposure and relevant attack paths.
Can cloud-hosted IPs be included?
Yes, provided the assets are owned or authorized by the client and any cloud-provider testing requirements are observed.
