Services
Cyber Defense
Cybersecurity assessments, hardening, and penetration testing designed to identify weaknesses, reduce attack surface, validate controls, and improve the organization's ability to withstand real-world threats.
One division, multiple ways to reduce cyber risk
Cybersecurity built around real operational risk
TIERS Cyber Defense combines assessment, security testing, hardening, remediation support, and advisory services. The goal is not to hand clients a scanner report. It is to identify material weaknesses, explain what they mean, help correct them, and validate the result.
Cybersecurity Assessments
A structured view of security posture, control gaps, identity risk, external exposure, and remediation priorities.

A security engagement should end with a clearer, stronger environment
TIERS Group can move from discovery to remediation support and retesting without forcing a client to restart with another vendor. When a compromise is identified, the engagement can also transition into digital forensics and evidence-focused support where appropriate.
Typical deliverables
- Executive risk summary
- Technical findings with evidence
- Prioritized remediation roadmap
- Configuration and hardening recommendations
- Retest and validation results
- Leadership findings briefing
How it works
Simple client experience. Disciplined technical process.
- 1
Initial inquiry
A short intake captures the organization, service need, timeframe, and high-level problem without requesting credentials or sensitive evidence.
- 2
Scope and authority
TIERS Group confirms goals, systems, ownership, exclusions, third-party dependencies, testing windows, and legal authorization.
- 3
Assess, test, or harden
The technical work is performed against the agreed scope using methods appropriate to the environment and business risk.
- 4
Findings and remediation
Results are translated into executive and technical guidance, with remediation priorities based on impact and practicality.
- 5
Retest and closeout
Where requested, TIERS Group validates corrective actions and documents whether material findings have been resolved.
Methodology
Grounded in recognized security guidance
Engagements can be aligned to recognized security frameworks and technical testing guidance based on the client environment and scope. Alignment does not imply certification or regulatory attestation unless specifically contracted.

Common questions
Before an engagement begins
Can TIERS Group penetration test any system a client gives us?
No. Testing requires written authorization from a party with authority over the specific targets. Third-party, cloud, software-as-a-service (SaaS), hosting, or managed infrastructure may require additional approval.
Can most Cyber Defense work be performed remotely?
Yes, many assessment, cloud, Microsoft 365, external testing, advisory, and review activities can be performed remotely. Internal network, wireless, physical, or certain controlled testing may require on-site access or a secure remote testing arrangement.
Does TIERS Group only identify problems?
No. Depending on scope, TIERS Group can help prioritize remediation, assist with hardening and corrective actions, and retest to validate that material findings were addressed.
What should be submitted through the website?
Only high-level business and security context. Do not submit credentials, passwords, evidence, regulated data, protected client information, or sensitive incident details through the public intake form.
