Why You Need a Penetration Test

Altius IT’s black box penetration test is the most realistic simulation of an external cyber attack available. Our cybersecurity & penetration testing experts are given zero prior knowledge of your systems, network architecture, source code, or credentials, and they target your organization exactly as a real-world attacker would.

Using only your organization’s name and publicly available information, our team identifies, targets, and attempts to exploit vulnerabilities across your external-facing assets. This approach provides the most honest assessment of your security posture because it tests what an attacker actually sees and can do, not what your internal team believes is secure.

A black box penetration test answers the critical question every organization needs answered: if a skilled attacker targets us today, what can they get into?

What Is Black Box Penetration Testing?

In a black box penetration test, the tester receives no internal information about the target environment. There are no network diagrams, no credentials, no source code, and no guidance on what systems are in scope beyond client-provided target identifiers such as public IP addresses, domain names, or URL ranges. The tester must discover everything independently, just as a malicious attacker would.

Black Box (this service)

No prior knowledge. The tester discovers and attacks the target from the outside with no internal information. Simulates a real external threat actor.

Gray Box

Limited credentials or partial internal knowledge provided. Simulates a compromised employee account or a threat actor who has gained initial access. Available as part of our Cybersecurity Audit Penetration Test and Network Security Audit services.

White Box

Full internal access, documentation, and credentials provided. Used for configuration reviews and compliance audits. Available as part of our IT Security Audit, Information Security Audit, and Network Security Audit services.

What We Test

Where We Test, the Way an Attacker Works

You provide only the assets to be tested: public IP addresses, domain names, or web application URLs. Our team works through four areas, following the phases of the Penetration Testing Execution Standard.

Reconnaissance & Discovery

Open-source intelligence (OSINT) gathering on your organization, domains, employees, and technology stack
DNS enumeration, subdomain discovery, and zone transfer testing
Public-facing asset identification and fingerprinting (web servers, mail servers, VPN gateways, cloud services)
Exposed credentials and sensitive data discovery (data breach databases, code repositories, paste sites, dark web)
SSL/TLS certificate analysis and related infrastructure mapping
Search engine and public records analysis for information leakage

Network Perimeter Testing

Full TCP and UDP port scanning across all provided IP ranges
Service enumeration and version identification on all discovered open ports
Firewall rule analysis and bypass testing
VPN gateway security evaluation (IKE enumeration, authentication testing, known vulnerability exploitation)
Remote access service testing (RDP, SSH, Telnet, remote management interfaces)
Mail server security (open relay testing, SMTP enumeration, SPF/DKIM/DMARC validation)
DNS server security (cache poisoning, zone transfer, DNSSEC validation)

Web Application Testing

OWASP Top 10 vulnerability assessment (SQL injection, cross-site scripting, broken authentication, security misconfigurations, and more)
Authentication and session management testing (brute force, credential stuffing, session fixation, token predictability)
Input validation testing across all user-accessible forms, parameters, and headers
API endpoint discovery and security testing (REST, GraphQL, SOAP)
File upload and download vulnerability testing
Server-side request forgery (SSRF) and server-side template injection (SSTI) testing
Business logic flaw identification (privilege escalation, access control bypass, workflow manipulation)
Content security policy, CORS configuration, and HTTP security header evaluation

Exploitation & Validation

Active exploitation of identified vulnerabilities to confirm real-world impact
Privilege escalation attempts from any foothold gained
Lateral movement testing if initial access to internal resources is achieved
Data exfiltration simulation to demonstrate what an attacker could access or steal
Chaining of multiple lower-severity vulnerabilities to demonstrate compound risk
All exploitation is performed under agreed-upon rules of engagement to prevent disruption to your operations

Our Testing Methodology

PTES (Penetration Testing Execution Standard)Our engagement follows the PTES phases: pre-engagement interactions, intelligence gathering, threat modeling, vulnerability analysis, exploitation, post-exploitation, and reporting.
OWASP Testing GuideWeb application testing follows the OWASP Testing Guide methodology for complete coverage of web-specific vulnerabilities.
NIST SP 800-115Our technical assessment approach aligns with NIST’s Technical Guide to Information Security Testing and Assessment.
MITRE ATT&CK FrameworkFindings are mapped to MITRE ATT&CK techniques to help your team understand the attacker’s perspective and prioritize defenses accordingly.

What You Receive

Our deliverables go beyond a list of vulnerabilities. You receive a complete picture of your external risk exposure:

Executive SummaryA non-technical overview of findings, overall risk rating, and strategic recommendations for leadership and board-level reporting.
Technical Findings ReportEach vulnerability documented with severity rating (Critical, High, Medium, Low, Informational), technical evidence including screenshots and request/response captures, proof-of-concept details, and step-by-step remediation guidance.
Attack NarrativeA chronological walkthrough of the tester’s approach, showing how vulnerabilities were discovered, exploited, and chained together.
Remediation RoadmapA prioritized action plan organized by severity and effort, so your team knows exactly what to fix first.
MITRE ATT&CK MappingFindings mapped to specific ATT&CK techniques and tactics, providing context for how each vulnerability fits into a real attack scenario.
Retest ValidationAfter you remediate the findings, Altius IT performs a follow-up retest of critical and high-severity vulnerabilities to confirm they have been properly resolved.

What You Provide

The information you provide for a black box penetration test is intentionally minimal. We only need:

Public IP addresses or IP ranges to be tested
Domain names and web application URLs in scope
Any systems or IP addresses that must be excluded from testing (out-of-scope assets)
Preferred testing window (business hours, after hours, or unrestricted)
Emergency contact information in case an issue arises during testing

You do not provide network diagrams, credentials, source code, or any internal documentation. That is the point of a black box test.

Rules of Engagement

Every black box penetration test begins with a signed rules of engagement document that defines the scope, timing, boundaries, and communication protocols for the engagement. This ensures testing is conducted safely and professionally:

Defined scope (IP addresses, domains, and applications authorized for testing)
Excluded assets and systems that must not be tested
Testing window and notification procedures
Escalation and emergency stop procedures
Data handling and confidentiality requirements
Agreed-upon exploitation limits (for example, whether to attempt data exfiltration or stop at proof of access)

Who Needs a Black Box Penetration Test?

A black box penetration test is the right engagement for organizations that want to know how they look to an outside attacker. It is ideal for:

Organizations that need to validate their perimeter defenses against realistic attack scenarios
Companies preparing for compliance audits that require or expect external penetration testing (PCI DSS, HIPAA, SOC 2, NIST, CMMC, ISO 27001)
Leadership teams that need an honest, unbiased assessment of external risk exposure
Organizations that have completed internal security improvements and want to verify their effectiveness from the outside
Companies in regulated or high-risk industries (financial services, healthcare, government contractors, energy, technology)
Organizations that have never had an external penetration test or are transitioning to a new security provider and want a fresh baseline

Combine With Other Services

A black box penetration test can be performed as a standalone engagement or combined with other Altius IT services for broader coverage:

Network Security AuditAdd a black box penetration test to validate your network perimeter after a white box review of your firewall rules, segmentation, and infrastructure configurations.
Web Application Security AuditPair a black box penetration test with a dedicated web application security assessment for deeper coverage of your web-facing assets.
Social Engineering AssessmentCombine with phishing simulations and pretexting to test both your technical defenses and your people.
Red Team Assessment ProgramIf you need more than a one-time test, move to a recurring program that combines penetration testing, social engineering, and adversary simulation cycle over cycle, with cumulative trend reporting.
