Security Architecture · Cyber Risk · Independent Advisory

Know your risk.
Build your defense.

Most assessments hand you a findings list and walk away. We deliver architecture reviews and risk assessments that tell you exactly where you're exposed, why it matters, and what to fix first.

Architecture Adversarial Design Review
Risk Business-Impact Focused
Advisory Independent Perspective

You might already think you're covered.

"We passed our compliance audit."
Compliance confirms controls exist — it doesn't tell you whether they're effective, consistently applied, or actually protecting your highest-value assets. A risk assessment answers those questions.
"Our architects already reviewed the design."
Internal reviews optimize for delivery. A security architecture review looks at the same design through an adversarial lens — examining trust boundaries, privilege paths, and failure modes your team isn't paid to find.
"We're pre-revenue — budget is tight."
A Cyber Risk Assessment starts at $5–8K and surfaces the exposures investors and enterprise customers will ask about in due diligence. Far cheaper to find them now than mid-deal.
"We already have a security team."
Internal teams are closest to the environment — which makes independent review more valuable, not less. We bring outside perspective, dedicated focus, and no organizational blind spots.

Built by practitioners,
not theorists.

AppSec Sentinel was founded by a SANS GIAC-certified security engineer with deep operational experience across application security, cloud infrastructure, and compliance — working at the intersection of all three where most firms only cover one.

Our practice is grounded in real-world security operations at enterprise scale — architecting secure workflows for media production environments, enforcing network segmentation and endpoint hardening across hybrid cloud deployments, and conducting application security assessments including threat modeling and third-party penetration test coordination. That operational depth is what separates our findings reports from checkbox audits.

Operational Background
  • Cloud security and content transfer protections across hybrid environments
  • Vulnerability scanning across production environments — identifying misconfigurations, outdated components, and exploitable weaknesses
  • Application security assessments with threat modeling and pentest coordination
  • Internal documentation and evidence matrices supporting audit-readiness and operational resilience
  • Technical implementation mapping to control sets for certifications and ongoing risk management

Two services.
One clear outcome.

Security architecture reviews and cyber risk assessments built for organizations that need clear answers, not just a list of findings.

CORE SERVICE

Security Architecture Review

A structured evaluation of how your systems are designed to resist attack. We examine your network segmentation, identity and access model, data flows, and control boundaries — identifying architectural weaknesses before they become incidents. Delivered pre-build, pre-launch, or as a standing review against a growing environment.

  • Network segmentation and trust boundary analysis
  • Identity and access model review (roles, privilege paths, least privilege)
  • Data flow mapping and exposure analysis
  • Authentication and session architecture assessment
  • Control gap findings with architectural remediation guidance
  • Industry-standard control mapping for audit and compliance readiness
Threat Modeling Access Control Trust Boundaries Zero Trust
CORE SERVICE

Cyber Risk Assessment

A risk-first evaluation of your security posture across people, process, and technology. We quantify where your organization is exposed, prioritize by business impact, and translate technical findings into language your leadership and board can act on.

  • Asset inventory and criticality classification
  • Threat landscape analysis relevant to your industry and size
  • Control effectiveness evaluation across key domains
  • Risk register with likelihood and impact scoring
  • Executive risk summary and board-ready narrative
  • Prioritized remediation roadmap with ownership assignments

Pre-Build Security Design Advisory

Engage before a line of code ships. We review your planned architecture — API design, cloud infrastructure model, data storage decisions, third-party integrations — and surface security issues while they're still cheap to fix. Pure advisory, low overhead, high leverage.

  • Cloud infrastructure and service design review
  • API and integration security guidance
  • Secure-by-default configuration recommendations
  • Developer-ready findings with code-level context

How an assessment works.

01

Discovery Call

30 minutes. We learn your stack, your biggest fears, and where you are in your growth cycle. We scope accordingly.

02

Access & Kickoff

Read-only environment access. Architecture documentation and relevant system diagrams as needed. One-hour kickoff to align on scope and timeline.

03

Assessment

Automated tooling paired with deep manual analysis. We examine your environment, design, and controls through an adversarial lens — the step most assessments skip.

04

Report & Readout

Executive summary plus technical findings report. Live readout with your team. Every finding mapped to a control category and business context — no raw vulnerabilities without explanation.

05

Remediation Support

Optional 30-day post-assessment support window. Questions, PRs reviewed, re-tests on critical findings. Available as an add-on or included in the Program tier.

Two engagements. Clear scope.

Straightforward pricing with no enterprise bloat and no junior-team bait-and-switch.

Risk Assessment
$5K–$8K
One-time engagement

A focused cyber risk assessment for organizations that need to understand their exposure before a raise, audit, or enterprise customer review.

  • Asset inventory and criticality classification
  • Threat landscape analysis for your sector
  • Control effectiveness evaluation
  • Risk register with likelihood and impact scoring
  • Executive summary for board / investors
Ideal for: Pre-audit, due diligence prep, new CISO onboarding

Credentials that come from doing, not certifying.

Adversarial Architecture Thinking

Security architecture reviews require looking at a system the way an attacker does — tracing privilege paths, probing trust boundaries, and asking what breaks when a single control fails. That mindset comes from hands-on security operations, not just framework knowledge.

Most architecture reviews validate design intent. Ours pressure-test it.

Risk That Means Something to Leadership

Risk assessments fail when they stay technical. We translate findings into business impact — revenue exposure, regulatory consequence, operational disruption — so executives can prioritize with confidence and boards can govern effectively.

Our risk registers are built for decision-makers, not just security teams.

Operational Security Experience

Certified across penetration testing, web application security, and incident handling, with direct experience running security programs at enterprise scale — vulnerability management, compliance attestation, and third-party risk. We know what good looks like because we've built it.

Experience earned in production environments, not just labs.
