Vulnerability Assessment
A vulnerability assessment is a structured scan and review of your environment to identify known security weaknesses, validate exposure, and prioritise fixes before attackers exploit them. You get a clear, risk ranked view of what matters most across your systems, applications, and infrastructure.
What you get
Prioritised vulnerability register with severity and business impact
Clear remediation guidance for your IT team or provider
Evidence you can use for executive reporting and compliance alignment
Support to confirm patching and configuration is keeping pace with real world threats
Types of Vulnerability Assessments
Network Vulnerability Assessment
We scan internal and external network infrastructure to identify known vulnerabilities, missing patches, exposed services, and insecure configurations.
This includes servers, firewalls, routers, switches, and endpoints. The goal is to uncover weaknesses attackers routinely scan for and prioritise remediation before exploitation.
Best for
Organisations with on premise infrastructure, hybrid environments, or multi site offices.
SaaS Application Vulnerability Assessment
Modern organisations rely heavily on SaaS platforms such as Google Workspace, CRM systems, HR platforms, finance systems, and marketing tools.
We analyse all SaaS applications used across your organisation to assess:
- What data each application can access
β’ Third party OAuth permissions and risky integrations
β’ Over privileged access to sensitive information
β’ Exposure if a vendor or app is compromised
β’ Shadow IT and unmanaged SaaS usage
If a third party app is breached, the impact can extend directly into your core systems. We help you understand that risk clearly and prioritise controls.
Best for
Google Workspace environments, high SaaS usage businesses, and organisations managing sensitive customer or financial data.
Custom Built Application Vulnerability Assessment
Custom applications connected to the internet are prime targets for attackers, especially if they lack structured security testing and ongoing updates.
We evaluate custom web and business applications to uncover vulnerabilities such as:
- Authentication weaknesses
β’ Injection vulnerabilities
β’ Broken access controls
β’ Insecure APIs
β’ Misconfigured security headers
β’ Exposure aligned to OWASP Top 10 risks
Testing can be performed as an authorised or unauthorised user depending on your threat model.
Best for
Customer portals, internal business systems, booking platforms, franchise management systems, and industry specific tools.
Website Vulnerability Assessment
Websites are common entry points for attackers, particularly if they collect personal information, login credentials, or payment details.
We test your public facing website for vulnerabilities that could lead to:
- Website defacement
β’ Data breaches
β’ Unauthorised admin access
β’ Malware injection
β’ SEO poisoning
β’ Reputation damage
If your website collects PII or integrates with backend systems, the risk extends beyond the website itself.
Best for
Ecommerce businesses, service providers, and any organisation collecting user data online.
Remote Work & BYOD Vulnerability Assessment
Remote work and BYOD have expanded the attack surface significantly.
We assess your remote access posture including:
- Endpoint configuration risks
β’ Access levels of your confidential data
β’ Device encryption status
β’ MFA enforcement
β’ Remote access configuration
β’ VPN and identity security controls
The objective is to ensure your remote workforce meets the same security standard as your office environment.
Best for
Hybrid organisations, distributed teams, and businesses relying heavily on cloud access.
Cloud Infrastructure Vulnerability Assessment
Whether you use Google Cloud, Amazon Web Services, or Microsoft Azure, misconfigurations are one of the leading causes of breaches.
We evaluate cloud environments to identify:
- Publicly exposed storage
β’ Over permissive IAM roles
β’ Weak identity configuration
β’ Logging and monitoring gaps
β’ Insecure network segmentation
β’ Backup and recovery process
Cloud breaches often occur due to simple misconfigurations, not advanced exploits. We help you find and prioritise those gaps before they become incidents.
Best for
Organisations operating in public cloud or hybrid cloud environments.
Wireless Vulnerability Assessment
We assess your WiFi environment to identify weaknesses that could allow unauthorised access, lateral movement into internal systems, or interception of traffic.
We typically review and test for:
- Weak encryption and authentication settings
β’ Poorly secured guest networks and network segmentation gaps
β’ Rogue or unauthorised access points
β’ Risky SSID configurations and password practices
β’ Device connection controls and visibility gaps
β’ Wireless configurations that enable easy brute force or credential reuse attacks
Best for
Offices, shared workspaces, warehouses, and multi site environments where WiFi is a critical access path.
Our Vulnerability Assessment Method
Step 1 Scoping
We confirm what outcomes you need, define the systems in scope, and map how they fit into your wider environment so the results are relevant and actionable.
Step 2 Engagement
We run the assessment scans and validate the results so you are not left with noisy outputs. We keep communication clear so stakeholders know what is happening and when.
Step 3 Post engagement
We deliver prioritised findings and walk you through what to fix first, why it matters, and how to reduce risk quickly.Β All done either in person meeting or via a recorded video call
Why choose Sentry Cyber
We focus on practical risk reduction, not just a scan output.
You get prioritised findings your team can actually action.
We can align outcomes to your broader security goals, including compliance reporting and roadmap planning.
Include our certifications as per pen test section
Vulnerability Assessment FAQs
What is a vulnerability assessment
A vulnerability assessment scans and reviews your environment to identify and prioritise known security weaknesses for remediation.
How is this different to penetration testing
Vulnerability assessments find and prioritise known weaknesses at scale. Penetration testing attempts to exploit weaknesses to prove real world impact. They work best together.
How often should we do vulnerability assessments
Most organisations run them regularly as part of ongoing security and patch management, with frequency based on scope, change rate, and risk profile.
Will this impact production systems
Scans can be tuned to reduce risk, with scheduling and throttling for sensitive systems. We confirm this in scoping.
Do you include a prioritised fix list
Yes. The deliverable is risk ranked so your team can focus on what reduces risk fastest.
Can you assess cloud and SaaS too
Yes. We can scope vulnerability assessment coverage across cloud infrastructure and key business systems, alongside your wider environment.
