Offensive Security
Find Out What an Attacker Could Actually Accomplish
Penetration testing goes beyond a scanner report. We manually validate weaknesses, chain them into realistic attack paths, and show what a motivated attacker could reach in your environment.
Testing vs. Scanning
A scanner finds candidates. Testing establishes consequence.
Automated scanning is a useful input. It is not a penetration test. A scanner reports that a service is missing a patch or that a configuration deviates from a baseline; it cannot tell you whether that condition is reachable, whether it can be combined with three other conditions, or what an attacker would obtain by using it.
Our penetration testing is performed by hand. Findings are validated through controlled exploitation where appropriate, and low-severity issues are chained together when they combine into something that genuinely matters. The result is a shorter list of things that are worth your engineering time.
What controlled testing means. Exploitation is performed within a written scope and rules of engagement agreed in advance, with defined testing windows, escalation contacts, and limits on destructive or disruptive activity.
No assessment can identify every vulnerability, and no test makes an organization secure. What a well-executed test does is give you evidence-based prioritization for the work you are already trying to do.
The hands-on testing is sharpened by Crimson, our in-house engine: it scores each host’s exploitability with machine-learning models and pulls live exploit intelligence for every candidate CVE, so triage and correlation are already done and the tester’s attention goes to the targets that genuinely warrant hands-on work.
Engagement Types
Penetration testing services
Each engagement type answers a different question. Most clients start with one and expand based on what the first test reveals.
01
External Penetration Testing
Evaluate Internet-facing systems from an external attacker's perspective. Testing covers what is actually exposed, whether that exposure is intentional, and what an unauthenticated attacker could do with it.
- Internet-facing attack surface discovery
- Exposed services and administrative interfaces
- Authentication weaknesses and credential attacks
- Vulnerability validation and controlled exploitation
- Externally reachable application weaknesses
- Information exposure and configuration issues
02
Internal Penetration Testing
Determine what an attacker could accomplish after obtaining an internal foothold, whether through phishing, a compromised endpoint, a third party, or physical access. This is where most real incidents are decided.
- Active Directory security
- Credential exposure and reuse
- Privilege escalation
- Lateral movement
- Network segmentation validation
- Attack-path analysis to critical assets
03
Web Application Penetration Testing
Manual testing of application security controls, with particular attention to authorization and business logic, which automated tooling consistently misses.
- Authentication
- Authorization
- Session management
- Input handling
- Business logic
- Application workflows
- Sensitive data exposure
04
API Penetration Testing
APIs frequently enforce authorization inconsistently across endpoints and expose more data than the user interface implies. Testing is performed against the API directly rather than through a front end.
- Authentication
- Object-level authorization
- Function-level authorization
- Excessive data exposure
- Input handling
- Business logic
- API integrations and trust relationships
05
Red Team / Adversarial Simulation
Objective-driven testing designed to evaluate prevention, detection, and response against realistic attack activity. Rather than enumerating vulnerabilities, a red team engagement pursues a defined objective and measures how the organization performs against it.
- Objective-based scenarios
- Realistic attacker tradecraft
- Detection and response evaluation
- Multi-stage attack execution
- Post-engagement debrief with defenders
06
Wireless Security
Evaluate wireless authentication, encryption, configuration, segmentation, and unauthorized exposure, including whether guest and corporate networks are actually separated the way the design says they are.
- Wireless authentication and encryption
- Enterprise wireless configuration
- Guest and corporate segmentation
- Rogue and unauthorized access points
- Client-side wireless exposure
07
Social Engineering / Phishing
Assess how the organization responds to credential-harvesting and pretext-based attacks, and whether the technical controls behind the human layer contain the result.
- Phishing campaigns
- Credential-harvesting scenarios
- Pretext-based approaches
- Reporting and response evaluation
Technical Assessments
Vulnerability and network assessments
Not every engagement needs full exploitation. When you want technical coverage and validated findings without a complete penetration test, these are the lighter-touch options — and they pair naturally with a program-level gap assessment.
01
External Vulnerability Assessment
Identify and manually validate vulnerabilities affecting Internet-facing infrastructure, including exposure that has accumulated without anyone intending it.
- Attack surface enumeration
- Vulnerability identification and validation
- Exposed services and interfaces
- Certificate and encryption configuration
- Information exposure
- Prioritized remediation plan
02
Internal Vulnerability Assessment
Identify vulnerabilities, missing patches, insecure configurations, and internal technical risk across servers, workstations, and network infrastructure.
- Missing patches and unsupported software
- Insecure configurations
- Weak or exposed credentials
- Legacy protocols and services
- Endpoint and server hardening gaps
- Prioritized remediation plan
03
Firewall & Network Security Review
Firewall rule sets accumulate. A review establishes what access actually exists today versus what the network diagram claims.
- Firewall rules
- Excessive access
- Segmentation
- VPN configuration
- Administrative access
- Internet exposure
How Engagements Run
A predictable process, from scoping to retest
Scoping
We define targets, objectives, testing windows, rules of engagement, and escalation contacts in writing before any testing begins.
Testing
Reconnaissance, manual analysis, validation, and controlled exploitation. Critical findings are reported immediately rather than held for the final report.
Reporting
An executive summary for leadership and detailed technical findings with evidence, risk rationale, and specific remediation guidance.
Debrief
A working session with your technical team to walk through attack paths, answer questions, and agree on remediation priorities.
Retest
Validation that remediated findings are actually resolved, which is often what customers, auditors, or insurers want to see.
Scoping-Based Pricing
Engagements are scoped according to the systems involved, technical complexity, testing depth, delivery requirements, and reporting needs.
Common questions
How large does our environment need to be?
There is no minimum. A focused external test of a small Internet-facing footprint is a legitimate engagement, and it is often the right first step for an organization that has never had testing performed.
Can testing be performed remotely?
Most testing is delivered remotely, including internal penetration testing, which is typically performed through a temporary connection or a device placed on your network. On-site work is available where an engagement genuinely requires it, such as wireless or physical assessments.
Will testing disrupt production systems?
Testing is conducted within agreed rules of engagement that define what is permitted, when testing occurs, and which activities are excluded. Where a technique carries meaningful risk of disruption, it is either performed in a controlled window or excluded by agreement.
We already run vulnerability scans. Do we need a penetration test?
They answer different questions. Scanning tells you what conditions exist across a broad surface. Penetration testing tells you which of those conditions are reachable, which can be combined, and what an attacker would gain. Many organizations run both, on different cadences.
Do you subcontract to other consulting firms and MSPs?
Yes. We support MSPs, MSSPs, and consulting firms that need specialized or overflow security testing capability, including white-label delivery arrangements where appropriate.
