OSINT Reconnaissance & Vulnerability Assessment Service
Before an adversary maps your organization – we do it first. Recosint’s reconnaissance and vulnerability assessment service combines advanced OSINT techniques with systematic security analysis to identify every exposed asset, misconfigured system, and exploitable weakness across your external attack surface – delivering a prioritized, actionable remediation report your security team can act on immediately.
What This Service Covers
1. External Attack Surface Mapping
Comprehensive identification of all internet-facing assets - domains, IP ranges, cloud infrastructure, and third-party services. Reveals shadow IT, forgotten systems, and unmonitored assets that introduce security risk.
2. Port Scanning & Service Enumeration
Systematic probing to identify open ports and running services across TCP and UDP protocols. Service fingerprinting determines exact software versions and associated vulnerabilities for targeted assessment.
3. Web Application Security Testing
In-depth analysis identifying injection flaws, broken authentication, cross-site scripting, insecure configurations, and business logic errors - combining automated scanning with manual verification.
4. Subdomain Discovery & DNS Enumeration
Advanced enumeration revealing all subdomains, DNS records, mail servers, and name configurations - often uncovering development environments, staging servers, and legacy systems still publicly accessible.
5. API Endpoint Discovery & Testing
Identification of exposed API endpoints followed by security testing for authentication bypasses, excessive data exposure, rate limiting issues, and injection vulnerabilities that provide direct backend access.
6. IoT Device & Webcam Discovery
Specialized scanning to locate internet-connected IoT devices, IP cameras, and embedded systems that frequently ship with default credentials or outdated firmware.
Who Needs This Service
Pre-Deployment Security Validation
Assess new applications before production deployment - identify vulnerabilities when fixes are least costly.
Regulatory Compliance
Meet assessment requirements for PCI DSS, ISO 27001, SOC 2, HIPAA, and GDPR through systematic vulnerability management.
Merger & Acquisition Due Diligence
Evaluate acquisition targets' security posture to quantify cybersecurity risk and inform valuation decisions.
Incident Prevention
Proactively identify and close security gaps attackers commonly exploit - reducing breach likelihood and incident response costs.
Our Assessment Process
1. Initial Scoping & Authorization
Detailed consultation to define testing scope, identify critical assets, and establish legal authorization before any assessment activities begin.
2. Asset Discovery & Reconnaissance
Systematic identification of your complete attack surface through DNS enumeration, subdomain discovery, port scanning, service fingerprinting, and technology stack identification.
3. Vulnerability Identification & Validation
Thorough security testing with manual verification. Each vulnerability validated to eliminate false positives and assessed for real-world exploitability.
4. Risk Analysis & Prioritization
Vulnerabilities mapped to business impact, compliance frameworks, and threat intelligence to establish risk-based remediation priorities.
5. Reporting & Remediation Guidance
Comprehensive documentation with technical details, proof-of-concept evidence, CVSS scores, and a prioritized remediation roadmap with estimated effort levels.
What You Receive
Executive Summary Report
Business-focused document communicating overall security posture, critical findings, and strategic recommendations without requiring technical expertise.
Technical Vulnerability Report
Detailed documentation of every identified vulnerability with technical descriptions, exploitation scenarios, remediation guidance, and compliance references.
Evidence Package
Screenshots, network captures, and proof-of-concept artifacts demonstrating each vulnerability for audit requirements and remediation verification.
Remediation Roadmap
Prioritized action plan sequencing remediation activities based on risk severity, exploitation likelihood, and organizational capacity with estimated timelines.
Ethical & Compliance Standards
All assessment activities are conducted strictly within defined scope after explicit written authorization – never beyond agreed boundaries. Our techniques are calibrated to identify vulnerabilities without causing system instability or service disruption. All findings are treated with strict confidentiality, encrypted in transit and at rest. Methodologies align with OWASP Testing Guide, PTES, NIST SP 800-115, and PCI DSS vulnerability scanning standards.

Frequently Asked Questions
What is the difference between vulnerability assessment and penetration testing?
Vulnerability assessment identifies and catalogs security weaknesses across your infrastructure with severity ratings and remediation guidance. Penetration testing actively exploits vulnerabilities to demonstrate real-world attack impact. Assessments provide broader coverage and are conducted more frequently, while penetration tests are deeper but more targeted.
How long does a vulnerability assessment take?
Duration depends on infrastructure scope and complexity. Small organizations typically require 3-5 business days, while large enterprises may need 2-4 weeks. The scoping consultation establishes realistic timelines based on your specific environment.
Will a vulnerability assessment disrupt our business operations?
Modern assessment techniques minimize operational impact through careful timing, rate limiting, and IT coordination. Testing windows are scheduled during low-traffic periods and coordinated with your security team to prevent false positive incident responses.
How are vulnerabilities prioritized when many are discovered?
Prioritization considers exploitability in your environment, system accessibility, data sensitivity, compensating controls, and public exploit availability beyond CVSS scores alone. Critical vulnerabilities on internet-facing systems with known exploits receive highest priority.
What happens if critical vulnerabilities are found during assessment?
Critical vulnerabilities posing immediate risk are reported to designated contacts via secure channels immediately upon validation — without waiting for the final report. This enables emergency patching or compensating controls. The assessment can be paused for emergency response if necessary.
