Vulnerability Assessment Services
Andersen's vulnerability assessment services detect and validate vulnerable software, insecure configurations, and exposed services across IT infrastructure, web and mobile applications, and cloud assets. Security teams gain clear vulnerability visibility, risk-based remediation priorities, and reduced exposure confirmed by retesting.
Vulnerability assessment at a glance
Andersen has run cybersecurity engagements for 19+ years, giving clients a proven vulnerability assessment process for detecting vulnerabilities across regulated industries and complex IT environments.
Andersen has delivered 300+ security projects across networks, applications, and cloud platforms, building the expertise clients rely on to detect common vulnerabilities before cyber threats exploit them.
Vulnerability assessment services we provide
Andersen's vulnerability assessment services cover six scope areas, and each one combines automated scanning with manual validation to reduce security risks across networks, applications, and cloud infrastructure.
Andersen scans internal and external networks, servers, and firewalls to detect network vulnerability issues such as open ports, weak protocols, and misconfigured devices. Clients receive a prioritized list of weak points, reducing the risk of attackers pivoting through the internal network.
Scope includes:
- External network perimeter scanning;
- Internal segmentation and firewall review;
- Service and protocol exposure checks.
Andersen tests web applications for injection flaws, broken authentication, and insecure session handling that expose sensitive data to attackers. Findings map to OWASP categories, giving development teams actionable insights to fix the most critical weaknesses before release.
Scope includes:
- OWASP Top 10 coverage;
- Authentication and session testing;
- Business logic abuse checks.
Andersen reviews Application Programming Interface (API) endpoints for broken access control, excessive data exposure, and weak rate limiting that put backend systems and sensitive data at risk. Teams get a prioritized fix list that closes gaps commonly exploited across web and mobile applications.
Scope includes:
- Access control and authorization checks;
- Data exposure and rate-limiting review;
- Schema and endpoint mapping.
Andersen assesses iOS and Android applications for insecure data storage, weak encryption, and unsafe API calls that expose user data on personal devices. Clients get a fix plan covering the app binary, backend services, and stored data, lowering compliance and reputational risk.
Scope includes:
- Static and dynamic mobile testing;
- Local storage and encryption review;
- Backend and API call analysis.
Andersen audits AWS, Azure, and Google Cloud environments for exposed storage buckets, excessive Identity and Access Management (IAM) permissions, and open security groups. Clients receive prioritized findings that reduce misconfiguration risk and support a stronger cybersecurity posture across the IT environment.
Scope includes:
- Storage and IAM permission review;
- Network security group analysis;
- Configuration baseline comparison.
Andersen scans container images, registries, and Kubernetes clusters for outdated packages, privileged containers, and exposed control-plane services. Development teams get a remediation guidance report to close these gaps before deployment, so new vulnerabilities do not reach production.
Scope includes:
- Image and registry scanning;
- Cluster configuration review;
- Runtime privilege checks.

Benefits of vulnerability assessment services
Reduce exposure across the attack surface
A proactive approach to scheduled assessments shrinks the attack surface: internet-facing gaps close first, and each retest confirms that an exposed service is actually gone rather than just marked fixed in a ticket.
Strengthen overall security posture
Your security posture becomes a trackable metric instead of a one-time snapshot: every scan cycle is scored against the CVSS severity scale and compared with the prior baseline, so you see whether new fixes close gaps faster than new vulnerabilities appear. Stronger cyber defenses show up as a rising trend line your leadership can review release over release, not just a list of closed tickets.
Focus remediation on business-critical risks
Security teams get findings ranked by exploitability and asset value instead of a flat vulnerability list, so engineering time goes first to internet-facing flaws already listed in CISA's Known Exploited Vulnerabilities (KEV) catalog.
Support compliance and audit readiness
Mapped findings align to ISO 27001 Annex A and SOC 2 trust criteria, so audit teams reference one evidence set instead of rebuilding proof for every compliance cycle, cutting audit prep time.
Improve security planning and decisions
Trend reports show new vulnerabilities and recurring weak points by asset group, giving security leaders the data to plan budgets, staffing, and remediation timelines around real risk instead of guesswork.
Security risks a vulnerability assessment can identify
Each category below is a place where exposures hide, so security teams can assess which ones create the most risk and close them before an attacker finds them.
Vulnerability visibility across the attack surface
External networks, cloud assets, and forgotten subdomains often sit outside inventory tools, leaving security teams blind to systems attackers can reach first. Mapping the full attack surface closes that visibility gap before an incident forces the discovery.
Internet-facing systems and services
Open ports, exposed admin panels, and forgotten test environments on internet-facing servers give attackers an easy entry point. Andersen helps teams identify these systems early, so IT staff close or restrict access before exposure turns into an incident.
Software versions and patch status
Outdated operating systems, unpatched applications, and end-of-life software carry known, exploitable flaws that automated scanning can flag in minutes. Tracking patch status keeps servers and endpoints off the easiest target list for opportunistic exploitation.
Security configurations and controls
Weak passwords, disabled logging, and default credentials on servers and network devices bypass otherwise solid defenses. Reviewing configurations against a security baseline closes gaps that policy documents alone cannot fix.
Vulnerability relationships and attack paths
A single low-severity flaw rarely causes a breach, but chained with a misconfiguration and stolen credentials, it can open a full attack path to sensitive systems. Mapping these chains without running a live attack simulation shows which fixes break them fastest.
Vulnerability exposure across critical assets
Databases, domain controllers, and production servers carry the most business impact if compromised, yet they are not always scanned as often as edge systems. Prioritizing critical assets keeps databases and other high-value systems in scope for every assessment cycle.
