Why Cipher01

Built for teams that need results they can defend

Goal-driven, not checklist-driven

Engagements are scoped around the outcomes that matter to your business and mapped to real risk — not a generic template run against every host.

Findings you can act on

Every issue is risk-ranked with clear reproduction steps and specific remediation guidance, so your team knows what to fix first and why.

Senior practitioners

Testing and advisory work is led by experienced security professionals who can brief both engineers and leadership on what the results mean.

Services

A full-spectrum security practice

Offensive testing, governance and compliance, security leadership, and response — plus the IT support that keeps day-to-day operations steady.

Penetration Testing (VAPT)

Simulated real-world attacks against external, internal, web, and mobile environments to find exploitable weaknesses first.

Vulnerability Assessment

Systematic identification, classification, and prioritization of vulnerabilities across your infrastructure.

GRC & Compliance Consulting (ISO 27001)

Gap assessments, control implementation, and audit-readiness support for ISO 27001-aligned ISMS programs.

vCISO (Virtual CISO)

Fractional access to senior security leadership: strategy, risk management, and program oversight.

IT Services

Broader IT consulting and systems support: infrastructure guidance and project-based IT work.

Our Approach

A consistent methodology, engagement to engagement

Every project follows the same four phases. The depth changes with scope; the discipline does not.

01

Discovery

We define scope, objectives, and rules of engagement with your team, then map the assets, data flows, and threat scenarios that actually matter to your business. Testing is aimed at real risk, not a generic list.

02

Assessment

We review architecture, configurations, and controls to understand your current posture and where exposure concentrates. This frames the hands-on work and separates theoretical issues from practical ones.

03

Testing

We safely attempt to exploit identified weaknesses using manual, goal-driven techniques supported by tooling, chaining findings the way an attacker would to demonstrate genuine impact rather than raw scanner output.

04

Remediation Guidance

You receive risk-ranked findings with clear reproduction steps and specific, prioritized fixes. We debrief your technical and leadership stakeholders and re-test remediated items to confirm closure.

FAQ

Common questions

We start with a discovery conversation to understand your objectives, environment, and any compliance drivers. From there we propose scope, rules of engagement, and a timeline. Testing targets the assets and scenarios that carry real risk rather than a fixed checklist.
