The average organisation has over 1,000 exploitable vulnerabilities across its IT environment at any given time. Vista InfoSec’s CREST-approved vulnerability assessment services find, classify, and prioritise every one — so your team fixes what matters most, first.
Our teams across the US, UK, Singapore, and India support clients through every timezone and regulatory context.
Vulnerability Assessment is a systematic process of identifying vulnerabilities in systems, applications, and network infrastructures. It is a process of reviewing systems and networks that are susceptible to any vulnerabilities. The assessment helps the organization determine security flaws, risk exposure, and assets that are potentially exposed to Cybersecurity breaches.
As a CREST Approved organization, VISTA InfoSec takes pride in delivering Vulnerability Assessment services that adhere to the highest industry standards, ensuring comprehensive and reliable evaluations of your IT infrastructure
The Vulnerability Assessment process can help identify and fix security issues and further counter surprise attacks. Performing the Assessment frequently will validate the effectiveness of the existing security controls and ensure a high-security posture of your infrastructure. It is an important step towards limiting the Cybersecurity threats and other risk exposure against your organization.
A vulnerability assessment is the systematic process of identifying, classifying, and prioritising security weaknesses across your IT environment — before attackers find and exploit them. It is the foundation of every mature cybersecurity programme.
A vulnerability assessment (VA) is a structured security review that identifies known weaknesses — unpatched software, misconfigurations, weak authentication, exposed services, and insecure settings — across your networks, systems, applications, and cloud environments. Using CREST-approved methodologies and industry-standard tools aligned to CVE, CVSS, and CWE, Vista InfoSec delivers a prioritised risk register with clear remediation guidance for every finding.
A vulnerability assessment identifies and classifies weaknesses — it tells you what vulnerabilities exist and how severe they are. A penetration test goes further by manually exploiting those weaknesses to prove they are real attack paths with demonstrated business impact. Most organisations should begin with a vulnerability assessment to establish a risk baseline, then use penetration testing to validate the most critical findings. Vista InfoSec offers both, and many clients combine them in a VAPT engagement.
60% of breaches exploit vulnerabilities for which a patch was already available. The problem isn’t that organisations don’t patch — it’s that they don’t know which vulnerabilities exist or which ones are most dangerous. PCI DSS, ISO 27001, SOC 2, HIPAA, CMMC, and DORA all mandate regular vulnerability assessments. Beyond compliance, a VA is the fastest, most cost-effective way to reduce your real-world attack surface before an incident forces the issue.
From a single-environment scan to an enterprise-wide, recurring vulnerability management programme — Vista InfoSec delivers CREST-approved assessments with the context, prioritisation, and remediation support that generic scan reports never provide.
Credentialed vulnerability assessment using authenticated access to your systems — delivering dramatically more complete and accurate results than unauthenticated scans. With authentication, our scanners can assess installed software versions, registry settings, local user accounts, patch levels, and configuration compliance that perimeter scans entirely miss. Fewer false positives, more real findings, better prioritisation.
The difference between a raw scan output and a Vista InfoSec report is the work that happens between. We validate every finding — eliminating false positives, contextualising each vulnerability to your specific environment, and scoring risk based on asset criticality, not just CVSS score alone. You receive an executive summary, technical findings, and a remediation roadmap ordered by real risk — not just severity colour.
Point-in-time assessments show your risk on the day of the scan. Continuous vulnerability management shows your risk every day. Vista InfoSec deploys lightweight scanning agents or API integrations across your environment to maintain a live vulnerability register — alerting your team when new critical CVEs emerge that affect your assets, and tracking remediation status in real time.
Vulnerability assessment reports produced specifically to satisfy external auditor and compliance framework evidence requirements. We format findings, remediation timelines, and scan evidence to match what PCI DSS Requirement 11.3, ISO 27001 Annex A 8.8, SOC 2 CC7.1, and CMMC assessors expect to see — so you never have to retest because your report didn’t satisfy the auditor’s evidence standard.
Finding vulnerabilities is only half the job. Vista InfoSec verifies that your team’s remediation efforts actually closed each vulnerability — retesting every finding after your patch cycle to confirm it is genuinely resolved. Remediation validation reports serve as evidence for compliance auditors, cyber insurance providers, and board-level risk reporting that your vulnerability programme produces real risk reduction.
The most complete security assessment available — combining a full vulnerability assessment with targeted manual penetration testing of your highest-risk findings. The VA identifies the full population of weaknesses; the pentest proves which ones are genuinely exploitable and demonstrates the real-world impact of a breach. Vista InfoSec’s VAPT engagements satisfy both VA and pentest requirements for PCI DSS, ISO 27001, and SOC 2 in a single integrated engagement.
Vista InfoSec holds CREST approval — the internationally recognised accreditation body for vulnerability assessment and penetration testing firms. CREST approval means our methodology, processes, tools, and analyst competency have been independently verified to meet the highest industry standards. For regulated industries and enterprise procurement, CREST approval is the baseline requirement.
Every Critical and High severity finding in a Vista InfoSec report has been manually validated before delivery. We don't hand you a raw scanner dump and call it an assessment. Our analysts review every finding for exploitability in your specific environment — if we can't validate a finding, we downgrade it or exclude it from your action items rather than waste your team's remediation effort on phantom risks.
A CVSS score of 9.0 on a development server with no internet exposure is a different risk from the same score on your payment processing system. Vista InfoSec contextualises every finding to your asset criticality, data sensitivity, and business function — giving you a prioritised action list that reflects actual business risk, not just vulnerability severity in isolation.
Vista InfoSec vulnerability assessment reports are structured to satisfy external auditor review for PCI DSS, ISO 27001, SOC 2, CMMC, and HIPAA compliance purposes. Our reports include scan scope documentation, tool and methodology disclosure, finding evidence, CVSS vector strings, and remediation timelines — every element auditors require without needing a retesting cycle because the report format was wrong.
Every Vista InfoSec vulnerability assessment includes one free retest within 90 days. After your team completes remediation, we retest every finding and deliver a remediation verification report confirming which vulnerabilities have been resolved. This closes the compliance loop — your auditor receives evidence that your VA programme produces real remediation, not just a list of findings that sits in a backlog.
Both are essential — but they answer different questions. Our consultants explain the key differences so you get the right assessment for your risk profile and compliance requirement.

The time between a vulnerability being disclosed and it being actively exploited in the wild has collapsed to an average of 15 days. New CVEs are published daily. Misconfigurations accumulate with every deployment. Without a regular, structured vulnerability assessment programme, your attack surface grows silently while your team works on everything else.
Questions we hear most often from organisations starting their Penetration Testing journey.
Vulnerability assessment costs depend on scope — number of hosts, IP ranges, applications, and cloud accounts included. A focused network VA for up to 50 hosts typically runs $2,000–$5,000. A comprehensive enterprise VA covering multiple environments (network, web app, cloud) typically ranges from $8,000–$25,000. Recurring quarterly or monthly programmes are priced with significant volume discounts. Vista InfoSec provides fixed-price proposals after a free scoping call — so you know the exact cost before engaging, with no open-ended day-rate billing.
Frequency depends on your environment's rate of change and your compliance requirements. PCI DSS requires internal and external vulnerability scans at least quarterly and after any significant change. ISO 27001 and SOC 2 require regular assessments — most auditors expect at least annual VAs for certification. In practice, the right frequency is quarterly for most organisations — enough to catch new CVEs affecting your patching cycle, track remediation progress, and maintain continuous compliance evidence. For high-change environments (active development, frequent deployments), monthly scanning is recommended.
A vulnerability assessment identifies and classifies weaknesses using scanning tools and manual validation — it produces a comprehensive list of what vulnerabilities exist, how severe they are, and what to fix. A penetration test goes further: certified testers manually exploit vulnerabilities to prove they are genuine attack paths and demonstrate real business impact. A VA is broader in coverage; a pentest is deeper on specific targets. Most organisations benefit from quarterly VAs for ongoing risk visibility and an annual pentest to validate their most critical findings are truly exploitable. Vista InfoSec's VAPT service combines both in a single integrated engagement.
A properly scoped and executed vulnerability assessment should cause no disruption to production systems. Vista InfoSec agrees on scan windows before engagement — typically scheduling intensive scans during off-hours for business-critical systems, using rate-limited configurations for sensitive network segments, and excluding specific systems where scan activity could trigger operational issues. We use professional-grade scanning tools configured to minimise network impact. If required, we can conduct assessments in a staging environment or schedule around your maintenance windows.
PCI DSS Requirement 11.3 mandates internal and external vulnerability scanning at least quarterly and after any significant change. External scans must be performed by a PCI SSC Approved Scanning Vendor (ASV). Vista InfoSec's external vulnerability assessments are conducted using ASV-approved methodology and include the required scan reports, dispute process documentation, and passing scan attestation that PCI DSS assessors and QSAs require. Our internal vulnerability assessments are formatted to satisfy internal scan evidence requirements under Requirement 11.3.1. We can also provide quarterly scanning programmes that cover all four PCI DSS scan cycles annually with a single engagement agreement.
Every Vista InfoSec vulnerability assessment report includes: an executive summary with overall risk rating, finding count by severity, and risk trend versus your previous assessment; a full technical findings section where each vulnerability has a CVSS v3.1 base score, CVSS vector string, affected asset and service, proof of existence, business impact statement, and specific step-by-step remediation guidance; a remediation roadmap prioritised by risk score with recommended SLAs for each severity tier; and a remediation tracking spreadsheet with owner assignment, due date, and status fields. Reports are formatted to satisfy PCI DSS, ISO 27001, SOC 2, and CMMC auditor evidence requirements without additional formatting work from your team.
