Adversarial testing

Measure how your defenses perform against a real objective.

Goal-driven attack simulation that tests people, process, and technology against realistic adversary behavior without unnecessary disruption.

01 / Overview

What is Red Teaming & Attack Simulation?

Goal-driven attack simulation that tests people, process, and technology against realistic adversary behavior without unnecessary disruption.

Hackstack Security delivers it as a scoped, agentic engagement: AI agents on local and client-approved API models expand coverage, our specialists test the logic and attack chains agents miss, and every finding is validated by a human, explained in business terms, and retested after you fix it.

  • AI agents plus manual testers
  • Human-validated findings only
  • Retest and closure status included
02 / Outcomes

What outcomes should you expect?

Every engagement is designed around the risk your team needs to understand and the action it needs to take.

01

Evidence of defensive effectiveness

02

Detection improvement opportunities

03

Executive-ready risk insight

03 / Coverage

What does red teaming testing cover?

Proven methodology plus the judgment needed to uncover context-specific risk.

01

Threat-led attack scenarios

02

External and internal attack paths

03

Social engineering planning

04

Detection and response validation

05

Assumed breach exercises

06

Purple-team debrief

04 / Timing

When should you run red teaming testing?

Test before a finding turns into a release delay, a customer escalation, or an incident.

01

Before a major launch, migration, or architecture change

02

When enterprise customers or partners request security evidence

03

After meaningful changes to identity, data, integrations, or infrastructure

04

When your team needs an independent view of real-world risk

05 / Technical research

Which questions do we test?

Frameworks support consistent coverage. The assessment remains driven by your architecture, trust boundaries, threat model, and business workflows.

Questions we test
  1. Can an adversary achieve the agreed objective using realistic techniques?
  2. Can an initial foothold be expanded through privilege escalation or lateral movement?
  3. Will defensive controls detect, investigate, and contain the activity?
  4. Are escalation and decision-making processes effective under pressure?
Evidence we produce
  • Reproducible request, response, configuration, or workflow evidence
  • Attack-path narrative connecting technical behavior to business impact
  • Control-focused remediation guidance and verification criteria
06 / Methodology

How does Hackstack Security test?

Testing is scoped, evidence-led, and designed to reduce risk without creating unnecessary disruption.

01

Context first

We learn the system, users, trust boundaries, and business objectives before testing begins.

02

Expert-led testing

Automation supports coverage. Human analysis finds the issues that depend on judgment and context.

03

Clear prioritization

Findings are ranked by exploitability, impact, and what matters to your organization.

04

Remediation partnership

We stay engaged through fixes, answer engineering questions, and validate closure.

07 / Deliverables

What will you receive?

Reports are written for the people who need to make decisions, fix issues, and demonstrate improvement.

Executive summary and risk narrative

Detailed technical findings

Risk rating and prioritization

Exploit evidence and reproduction steps

Developer-friendly remediation guidance

Retest status and closure validation

08 / FAQ

Red Teaming questions, answered.

Still unsure? Ask us directly and we will reply with a proposed scope.

What does Red Teaming & Attack Simulation include?

It covers threat-led attack scenarios, external and internal attack paths, social engineering planning, detection and response validation, assumed breach exercises, and purple-team debrief. Each engagement is scoped to your environment and ends with validated findings, remediation guidance, and a readout.

What will we receive at the end?

You receive an executive summary, detailed technical findings with exploit evidence and reproduction steps, risk ratings, developer-ready remediation guidance, and retest status. The goal is evidence of defensive effectiveness, detection improvement opportunities, executive-ready risk insight.

Which frameworks guide the testing?

Coverage is aligned with MITRE ATT&CK, NIST Cybersecurity Framework 2.0, CISA Red Team Assessments, then shaped by your architecture, trust boundaries, and business workflows.

Do you use AI agents or only manual testing?

Both. AI agents running on self-hosted local models, and on API-based models when you approve them, handle reconnaissance, surface mapping, fuzzing, and hypothesis generation, while our specialists test business logic and chained attacks manually. Every result is validated by a practitioner before it is reported.

Can you support remediation and retesting?

Yes. We walk your engineers through findings, answer implementation questions, and retest agreed fixes to document final status for stakeholders and auditors.
