Network Vulnerability Assessment
Uncover hidden risks in your network and unlock critical insights with a forensics-driven approach.
Why it matters
Network environments constantly change, and exposed services, outdated software, and misconfigurations are often introduced faster than they can be detected. Attackers actively scan for these weaknesses to identify easy entry points long before targeted attacks begin.
Our Network Vulnerability Assessment provides a structured, risk-focused view of security weaknesses across both internal and external networks. This service is ideal for maintaining baseline security hygiene and understanding exposure across the network.
What this covers
SISA’s vulnerability assessment services combine automated and manual scans and include component-level root cause analysis, network and system architecture review and redundancy evaluation in entire infrastructure. We assess:
Internet-facing and internal network assets
Exposed services and open ports
Outdated or vulnerable software
Common misconfigurations and weak protocols
Known vulnerabilities across operating systems and network services
Our Approach
We focus on what attackers are most likely to exploit, not everything a scanner can detect.
Asset Discovery & Scope Definition
We identify in-scope internal and external assets to ensure accurate and complete coverage.
Vulnerability Identification
We perform controlled vulnerability discovery using industry-standard techniques, supplemented by manual analysis where required.
Validation & Risk Analysis
Findings are reviewed to confirm relevance, reduce noise, and assess real-world exploitability.
Risk Prioritization
Vulnerabilities are ranked based on exposure, likelihood of exploitation, and business impact.
Reporting & Guidance
We deliver clear reports with remediation guidance to support effective risk reduction.
Key deliverables
Executive summary with exposure overview
Validated vulnerability findings
Risk-based prioritization of issues
Remediation recommendations
Optional follow-up assessment after fixes
WHY SISA
Why Our Network Vulnerability Assessment Is Different
Most assessments deliver long lists of vulnerabilities with little context. We focus on accuracy, relevance, and prioritization, helping teams fix what actually reduces risk.
PCI SSC authorized Approved Scanning Vendor (ASV)
CREST-accredited framework
A specialized non-intrusive ASV solution for a systematic and exhaustive assessment
Risk-based assessment, not raw scan output
Context-aware analysis aligned to asset criticality
Manual validation to reduce false positives

SISA’s Breach and Attack Simulation gave us practical visibility into how our security controls performed under real-world attack scenarios. The simulations across external, internal, and O365 environments helped us identify which controls were effective, where gaps existed, and what needed immediate attention. Because SISA’s detection capabilities were already integrated into our environment, we could also better understand how attacks were detected and handled across different stages of the simulation. What stood out most was the transparency of the engagement and the actionable guidance the team provided throughout the process.
