Penetration Testing

Penetration testing across your real attack surface.

You give us the systems you want tested and the access the engagement requires. We map the attack surface, test it in context, validate meaningful weaknesses, connect related exposure, and show you what to fix first.

Assessment coverage Six core penetration testing services
What you are buying

A penetration test that tells you where your environment can actually fail.

You get validated findings, technical evidence, attack-surface context, remediation direction, and retesting tied to the original issue.

You get validated findings. We focus on weaknesses that create credible security exposure, not on generating the longest possible scanner report.
You see how exposure connects. Your applications, APIs, infrastructure, email, cloud, and identity layers are assessed as parts of the same environment.
You get a result your team can act on. Evidence, impact, remediation direction, and retesting stay tied to the finding from discovery through closure.
What we test

You choose the surface. We put it under pressure.

You are not buying a generic vulnerability scan. You are giving Expugna a defined, authorized target and asking a direct question: where can this environment be broken, abused, or trusted too far?

Application Security

Web Application

You give us the application, authorized scope, and credentials when authenticated testing is required. We test authentication, authorization, sessions, workflows, file handling, client-side behavior, and the business logic that decides what users are allowed to do.

Testing coverage
Authentication flows
Access control
Session security
Business logic
Input handling
File operations
Client-side behavior
Configuration exposure
Application Security

API

You give us the API endpoint, specification or collection when available, and the roles you want tested. We go after the authorization model, object boundaries, token handling, schema assumptions, workflow logic, tenant isolation, and exposed functionality behind the interface.

Testing coverage
Endpoint inventory
Object authorization
Function authorization
Token handling
Schema-aware testing
Tenant isolation
Workflow abuse
Version exposure
Infrastructure Security

External Network

You give us the domains, hosts, IPs, or network ranges you authorize. We identify what you expose to the internet, determine what is actually running there, and test the services, protocols, versions, and configurations that create meaningful external risk.

Testing coverage
Host discovery
Port discovery
Service fingerprinting
TLS and certificates
DNS exposure
Remote access services
Version intelligence
Controlled validation
Messaging Security

Email Infrastructure

You give us the mail domain and deeper access when the engagement requires it. We assess the mail infrastructure, transport security, authentication controls, exposed services, webmail surface, and domain-level protections that determine how easily your email environment can be abused.

Testing coverage
MX infrastructure
SMTP security
SPF
DKIM
DMARC
MTA-STS
TLS reporting
Webmail exposure
Cloud Security

Cloud

You give us delegated access to the cloud environment you want assessed. We map the resources, identities, permissions, public exposure, storage, networking, secrets, and trust relationships that can turn one weak control into a much larger compromise.

Testing coverage
IAM relationships
Privilege paths
Public exposure
Storage controls
Network controls
Compute identities
Secrets exposure
Cross-account trust
Identity Security

Identity & SSO

You give us the identity flows, application endpoints, and test accounts required for the engagement. We test the layer that decides who you are, what you can access, how trust is established, and whether those boundaries still hold when they are deliberately challenged.

Testing coverage
OAuth 2.0
OpenID Connect
SAML
Token validation
Redirect handling
Federation trust
MFA workflows
Role boundaries

You do not need proof that a scanner ran. You need to know what can be reached, what can be abused, how far the exposure can go, and what you should fix first.

How we test

You define the boundaries. We do the work inside them.

Your engagement starts with explicit authorization and a clear scope. From there, Expugna turns the target into an assessment: understand the environment, test it in context, validate what matters, connect related weaknesses, and verify the fix.

Define the scope

You specify the systems, exclusions, credentials, testing window, and restrictions that govern the engagement.

Map the environment

We identify reachable assets, services, routes, APIs, cloud resources, mail infrastructure, identity endpoints, and relevant relationships.

Test with context

Credentials, roles, protocols, schemas, workflows, cloud identities, and trust relationships become part of the assessment where they matter.

Validate the findings

Potential weaknesses are evaluated for actual security significance and supported with technical evidence.

Correlate the exposure

Related assets, permissions, identities, and findings are connected so you can see root causes and larger attack paths.

Retest the remediation

Your remediation stays tied to the original finding so you get a direct answer on whether the exposed control was fixed.

What you get

You get a penetration test that changes what you do next.

You should leave an assessment with fewer questions, not more. Expugna gives you the affected assets, technical proof, security impact, remediation direction, priority, and retest status in one place.

You know what is real. Validated findings separate meaningful exposure from low-value detection noise.
You know what matters first. Severity is tied to access, privilege, data, exploitability, and business impact.
You know how the pieces connect. Cross-surface correlation exposes larger attack paths that isolated scans miss.
You know when the fix is done. Retesting records whether the original weakness is fixed, partially fixed, or still exposed.
Evidence

Technical proof

Requests, responses, screenshots, service data, timestamps, affected assets, and supporting context stay with the finding.

Remediation

Clear corrective direction

Your engineers get a direct explanation of what failed and what security control needs to change.

Reporting

Executive and technical views

Your decision-makers get the risk and business impact. Your technical teams get the detail required to act.

Verification

Retesting stays connected

Your remediation work remains tied to the original issue from discovery through verification.

Engagement controls

You stay in control of the test.

Authorized target scope Enforced
Explicit exclusions Enforced
Rate and concurrency limits Enforced
Testing window Enforced
Activity and evidence trail Recorded
Emergency stop Available
Built for serious environments

You should not have to choose between aggressive testing and disciplined execution.

You want an assessment that pushes hard enough to expose meaningful weaknesses without turning your production environment into a guessing game. That requires explicit authorization, controlled techniques, isolated execution, and a traceable record of what happened.

Your scope, access, testing restrictions, evidence, findings, and retest status remain tied to the engagement from start to finish.
