What is offensive security?

Offensive security uses authorised testing to identify and validate weaknesses in systems, applications, people or processes. The scope and methods are agreed before testing begins.

What is the difference between penetration testing and red teaming?

Penetration testing usually examines a defined technical scope for exploitable weaknesses. Red teaming works towards an agreed objective and may test how several weaknesses and control failures combine.

What is a purple team exercise?

A purple team exercise brings offensive and defensive teams together to test selected behaviours, review available telemetry and improve detection and response.

Can offensive testing affect production systems?

Active testing carries risk. Digisecuritas agrees permitted techniques, restricted systems, testing windows, stop conditions and escalation procedures before work begins.

Can you test social-engineering controls?

Yes, where the activity is expressly authorised. Participants, scenarios, communication channels, data handling and restricted themes must be agreed beforehand.

Can Digisecuritas test cloud environments?

Yes. The approved scope can include cloud identity, configurations, workloads, storage, network paths and management controls. Provider testing policies must also be respected.

Will automated scanning be used?

Automated tools may support discovery and coverage. Significant findings should be manually reviewed and validated according to the approved scope.

Do you provide retesting?

Yes. Retesting can verify whether agreed remediation addresses the original finding. The scope and timing should be confirmed as part of the engagement.

How long does an offensive security assessment take?

Timing depends on the assessment type, scope, environment, access and operating constraints. A schedule should be provided after scoping.

TEST THE QUESTION THAT MATTERS

The objective determines the right assessment

A vulnerability scan, penetration test and red team engagement answer different questions. Digisecuritas helps organisations choose a method according to the environment, risk, maturity and decision the assessment must support.

"Useful testing begins with a clear question, not a preferred technique."

Find technical weaknesses

Assess an application, API, cloud environment, network or defined set of assets.

Validate exploitability

Determine whether identified weaknesses can be used within the authorised scope.

Test an attack path

Assess whether separate weaknesses can be combined to reach a defined objective.

Measure detection and response

Evaluate whether responsible teams identify, investigate and contain realistic activity.

Exercise coordination

Test decisions across security, technology, business, legal and executive stakeholders.

AUTHORITY BEFORE ACTIVITY

Rules of engagement protect the organisation and the assessment

Rules of engagement define the permissions and constraints for security testing before work begins. They establish what can be tested, how far validation may proceed and when activity must stop. NIST defines rules of engagement as detailed guidelines and constraints established before a security test.

ASSESS THE RELEVANT ENTRY POINTS

Attack paths can cross several technology domains

Applications and APIs

Authentication, authorisation, business logic, data access and connected services.

External infrastructure

Internet-facing systems, remote services, exposed management paths and perimeter controls.

Internal networks

Identity, privilege, segmentation, administration and lateral access pathways.

Cloud environments

Identity, configuration, workloads, storage, management access and service relationships.

People and process

Approved social-engineering scenarios, verification procedures and escalation behaviour.

Physical access

Authorised testing of locations, access controls and the relationship between physical and digital security.

Every domain must be included only through explicit written authorisation. Social-engineering or physical testing is not included by default.

SEE HOW WEAKNESSES COMBINE

A low-severity issue can matter when it opens the next step

Exposure

An authorised test identifies a reachable application, service, user or location.

Initial access

A validated weakness provides a limited position inside the agreed scope.

Identity

The test determines whether access can reach additional accounts or privileges.

Movement

Approved validation examines whether trust relationships allow wider access.

Objective

The team determines whether the agreed target can be reached safely.

Evidence

The engagement records the path, affected controls and remediation priorities.

Validate a Critical Attack Path

FOCUS ON RELEVANT ADVERSARY BEHAVIOUR

Use threat intelligence to shape the scenario

Threat-informed testing selects behaviours according to the organisation's sector, technology, exposure and risk priorities. The goal is a credible test plan, rather than the largest possible list of techniques.

MITRE ATT&CK provides a knowledge base of adversary tactics and techniques based on real-world observations. It can support scenario design and defensive coverage analysis.

DEFINED TECHNICAL VALIDATION

Penetration testing for specific systems and environments

Risk-based penetration testing

Testing combines automated discovery with manual validation according to the approved scope. Findings should explain the affected asset, security consequence, evidence and required corrective action.

NIST SP 800-115 provides guidance for planning and conducting technical security tests, analysing findings and developing mitigation strategies.

Web application testing

Assess authentication, authorisation, workflows, data handling and server-side controls.

API security testing

Review access, object permissions, input handling, rate controls and business actions.

Mobile application testing

Assess approved mobile applications, supporting APIs, local storage and authentication flows.

Network penetration testing

Evaluate authorised external or internal infrastructure and trust relationships.

Cloud penetration testing

Assess approved identities, workloads, configurations and cloud service exposure.

Wireless security testing

Review authorised wireless networks, access control, segmentation and configuration.

Request Penetration Testing

OBJECTIVE-BASED TESTING

Define success before the red team begins

A red team engagement should test a meaningful security question. The objective, operational constraints and required evidence must be agreed before activity begins. CISA describes red team assessments as simulations of malicious cyber operations used to assess detection and response capabilities.

Agreed business objective

Reach a protected environment

Access a controlled test record

Demonstrate a privilege boundary failure

Test detection of approved activity

Starting assumptions

What the test team knows or controls at the beginning.

Permitted paths

Which technical, human or physical routes may be tested.

Safety constraints

Which actions, systems and data remain restricted.

Success evidence

What safely demonstrates that the objective was reached.

Social-engineering testing must be expressly authorised. The engagement should define approved pretexts, restricted themes, data collection and emergency contacts before activity begins.

Discuss a Social-Engineering Exercise

FOLLOW THE DEFENSIVE RESPONSE

A blocked technique and a detected technique provide different evidence

The assessment should record which controls prevented activity, which produced useful telemetry and which supported investigation. This helps distinguish missing controls from controls that exist but are not operating as expected.

Technique stage	Prevented	Logged	Detected	Investigated	Contained
Initial access	Observed	Observed	Partial	Not observed	Not observed
Execution	Partial	Observed	Observed	Partial	Not observed
Persistence	Not observed	Partial	Not observed	Not tested	Not tested

CONTROLLED EXECUTION

Testing must remain within the approved risk envelope

Written authorisation

Confirm the approving authority, entities, systems and permitted activity.

Restricted targets

Identify sensitive systems, accounts, people and data that must not be accessed.

Test windows

Agree dates, time zones, operating restrictions and change freezes.

Stop conditions

Define events that require immediate suspension and escalation.

Evidence protection

Control the collection, storage, access, transmission and deletion of test data.

Trusted communications

Maintain verified contacts for routine updates and urgent escalation.

REPORT WHAT TEAMS CAN ACT ON

Every significant finding needs context and proof

Verified finding

A clear description of the weakness, affected asset and security consequence.

Affected scope

Preconditions

Reproduction summary

Observed evidence

Business consequence

Recommended action

Do not publish live credentials, sensitive customer data or unnecessary exploitation detail in general report copies. Use controlled technical appendices where required.

PRIORITISE THE ATTACK PATH

Severity should reflect how the weakness affects the organisation

Exposure

How reachable is the weakness within the actual environment?

Exploitability

What access, conditions and capability are required?

Consequence

Which data, service, privilege or business process could be affected?

Dependency

Which remediation must happen before the attack path is meaningfully reduced?

Technical scoring may support prioritisation. The final decision should also consider business impact, available mitigations and the role of the finding within a wider attack path.

CLOSE THE LOOP

A report is useful when it leads to verified improvement

Confirm ownership

Assign a responsible team and decision-maker.

Understand the root cause

Determine why the control failed or was absent.

Plan remediation

Define the technical change, dependencies and expected evidence.

Implement safely

Complete the change through the organisation's approved process.

Retest

Validate the original finding within the agreed scope.

Check the wider path

Confirm that the remediation meaningfully reduces the demonstrated attack route.
