Vulnerability assessment for US businesses

Vulnerability assessment: continuous discovery, prioritization, and remediation you can prove.

Most businesses cannot say what vulnerabilities exist on their network right now, which is exactly the question a SOC 2 auditor, a cyber insurance underwriter, or an enterprise customer's security questionnaire will ask. Vulnerability assessment is the foundation layer of every security program: continuous identification of known vulnerabilities, prioritized by exploitability and business impact, and tracked through remediation. We deliver one-off assessments and ongoing continuous-monitoring programs, remotely, anywhere in the United States.

Vulnerability assessment scope

Six discovery scopes across your attack surface.

A complete vulnerability program covers every asset class an attacker could exploit. We scope each engagement to the layers that matter most for your business, and we will tell you plainly which ones matter less.

External attack surface

Internet-facing IP space, exposed services, public-facing web applications, DNS misconfiguration, certificate hygiene. Discovers what an attacker can see without credentials, which is also what your cyber insurer's scanning vendor sees before quoting your renewal.

Internal network

Servers, workstations, network devices, printers, IoT. Credentialed scanning for accurate version-and-patch identification. Discovers what an attacker could exploit after a single phishing click gives them an insider position.

Web applications

Authenticated and unauthenticated web application scanning. OWASP Top 10 categories, with business-logic flaws that automated tools cannot catch flagged for manual review rather than silently omitted.

Cloud configuration

Azure, AWS, and Microsoft 365 tenant configuration. Public storage buckets, weak conditional access, exposed administrative interfaces, identity-provider misconfiguration. Cloud findings are where most US mid-market breaches actually start.

Endpoint configuration

Endpoint hardening, missing patches, weak local policies, unauthorized software, USB controls. Assessed at scale through Intune or equivalent endpoint management rather than machine by machine.

Network device configuration

Firewall rule audits, switch and router configuration, wireless controller hardening, and configuration drift from your secure baseline. The devices nobody has reviewed since installation are usually the oldest findings.

Why businesses route vulnerability assessment through us

Four reasons IT leaders choose GR.

CVSS-prioritized, business-impact-weighted

Vulnerability scanners produce volume. We add prioritization: CVSS severity adjusted for your business context, which assets carry sensitive data, which face the internet, and which support critical operations. The output is actionable, not just exhaustive.

Remediation tracking, not just discovery

Most vulnerability programs find issues and never close them. We track every finding through remediation with status updates, re-scan to verify closure, and burndown reporting. The metric that matters is mean-time-to-remediate, not count-of-vulnerabilities.

Continuous-monitoring option

Annual scans miss vulnerabilities that emerge between cycles. The continuous-monitoring engagement scans monthly, alerts on critical new findings within 24 hours, and produces monthly burndown reports written for leadership, not just engineers.

Evidence your auditor and insurer can use

Reports are written to serve as compliance evidence: control mapping for SOC 2, HIPAA risk analysis, PCI DSS, and NIST 800-171 where relevant, and the recent-assessment documentation cyber insurance applications increasingly require. One engagement, several audiences.

When to assess vulnerabilities

Six triggers for a vulnerability assessment.

Compliance baseline

SOC 2, HIPAA, PCI DSS, and NIST 800-171/CMMC programs all expect periodic vulnerability assessment evidence, with findings tracked to remediation.

Pre-acquisition due diligence

Acquiring a business? Assess its IT environment to understand inherited security debt before close, while it can still change the price.

Post-incident validation

After a near-miss or an incident, scan to verify the exploited gap is closed and to find the adjacent ones.

Pre-launch validation

Before launching a new web application or cloud workload, baseline its security posture while fixes are still cheap.

Cyber insurance underwriting

Underwriters increasingly require recent vulnerability-assessment evidence, and external scan findings show up in your quote whether you knew about them or not.

Continuous-monitoring program

Mature security programs run continuous scanning as the foundation layer under penetration testing and detection.

How a vulnerability assessment runs

From scoping to remediation tracking, five steps.

  1. 1

    Scope and authorization

    2-3 days

    Define scope: which IP ranges, which applications, which cloud tenants. Credentials for credentialed scans, timing windows, and a signed authorization letter. Output: a written scope both sides have agreed.

  2. 2

    Discovery and scanning

    3-7 days

    Automated scanning across scoped assets, with credentialed scans where authorized for accurate findings. Timing agreed in advance so production is never surprised.

  3. 3

    Manual review of findings

    2-3 days

    Every high-severity finding is manually reviewed to remove false positives before it reaches the report. Confirmed false positives are excluded with documented rationale, not silently dropped.

  4. 4

    Prioritization and reporting

    3-5 days

    CVSS scores adjusted for business context. A written report with an executive summary, technical findings, a prioritized remediation roadmap, and a re-scan schedule, plus a debrief presentation.

  5. 5

    Remediation tracking and re-scan

    Ongoing

    Findings tracked through remediation with status updates. Re-scan after each remediation cycle to verify closure, and month-by-month burndown reporting on what remains open.

Vulnerability assessment FAQ

What buyers ask before engaging.

Vulnerability assessment is automated identification of known vulnerabilities, prioritized and reported. Penetration testing is manual exploitation of vulnerabilities to verify which are actually exploitable and what the impact would be. Assessment is broad and lower-cost; pen testing is deeper and produces verified attack narratives. Most mature programs run both: continuous vulnerability assessment as the foundation, annual penetration testing on top.

Continuous-monitoring programs scan monthly with critical-finding alerts within 24 hours. Less mature programs run quarterly or annual scans. The right cadence depends on your change frequency, your risk tolerance, and what your compliance framework or insurer expects. PCI DSS environments have their own defined scanning cadence requirements, which we map during scoping.

Generally no. Standard scans are non-disruptive. We agree timing for credentialed scans, typically off-hours in your time zone, and stay within written rules of engagement for any scan that could affect system load. Fragile legacy systems can be excluded or handled with reduced-intensity scanning.

Tenable Nessus, Rapid7 InsightVM, Qualys VMDR, and Microsoft Defender Vulnerability Management. Each has strengths; we deploy the one that fits your environment and compliance requirements, and the scanner licensing is part of the engagement rather than a separate purchase you have to make.

Every high-severity finding is manually reviewed before reporting. Confirmed false positives are excluded with documented rationale. The report contains verified findings, not raw scanner output, which is the difference between a 40-page report your team acts on and a 400-page export nobody reads.

Yes, as a separate or bundled engagement. Vulnerability remediation is often included in managed IT scope for our managed clients. A pure-discovery engagement produces the report; remediation is a separate workflow we can execute or hand to your in-house team with clear guidance per finding.

It produces the evidence those frameworks expect. SOC 2 auditors look for vulnerability identification and remediation tracking as part of the common criteria. The HIPAA Security Rule requires a risk analysis, and a technical vulnerability assessment is a standard component of one. PCI DSS has explicit scanning requirements. The report includes a control-mapping appendix for the frameworks that apply to you. We are an IT services firm, not an auditor or a law firm, so your assessor owns the interpretation; we own the technical evidence.

Directly. Applications and renewals increasingly ask when your last vulnerability assessment was performed and how findings were remediated. Underwriters also run their own external scans against your domains before quoting. Running the assessment first means you see what they will see, and fix it, before it prices your premium.

For external scanning, no, only authorization. For internal, endpoint, and cloud scopes we need scoped credentials or a lightweight scanner deployment, agreed and documented during scoping, and removed when the engagement ends. Everything is delivered remotely; there is nothing to host for us and nobody to badge in.

One-off assessments are scoped by attack surface: number of IPs, applications, and cloud tenants. Continuous-monitoring engagements are scoped per month, scaled by attack-surface size. Every engagement gets a custom quote after a scoping conversation, and we will tell you if a smaller scope covers your actual risk.
