Security Testing

Validation Through Adversarial Logic

The only reliable way to understand your true defensive posture is to test it the way an attacker would. STSG’s Security Testing services combine continuous vulnerability assessment with manual penetration testing to give your leadership a clear, evidence-based picture of where you’re protected — and where you’re exposed.

//WHY IT MATTERS //

The STSG Testing Guarantee:
Security Through Validation

We don't just hand you a list of problems. Every engagement is built on three commitments that turn testing into a plan of action.

List

Real Attacker Logic

We test the way threat actors do — the same tools and the same mindset — so what we find is what a real adversary would find, not a checklist theory.

List

Evidence, Not Theory

Every finding is backed by proof of concept, not assumption. You see exactly what was possible and how, so there's no guesswork about the risk.

List

A Roadmap, Not a Report

We don't just hand you a list of problems. Every engagement ends with prioritized, actionable next steps ranked by real business risk.

// WHAT'S INCLUDED //

What's Included in Managed Backup Strategies

Immutable architecture, air-gapped isolation, hybrid cloud redundancy, application-aware capture, and nightly verification — combined so a pristine copy of your data always survives.

List

The 3-2-1-1-0 Backup Standard

Three copies, two media types, one off-site and one offline immutable copy — verified with zero errors through automated recovery testing on every cycle.

List

Immutable Storage & Logical Air-Gapping

WORM object-lock and logical air-gapping create a recovery environment fully isolated from production — untouchable even by a compromised administrator.

List

Cloud Disaster Recovery & Hybrid Redundancy

On-site flash storage delivers rapid file and VM recovery, while simultaneous replication to encrypted cloud regions protects against local and regional outages.

// OUR CORE TESTING DISCIPLINES //

Don't Wait for a Breach to Find Your Weakness — Let STSG Find It First

Two complementary disciplines give you the full picture: automated breadth to catch every known gap, and human depth to prove what a determined attacker could actually achieve.

List
01

Vulnerability Assessment

Continuous, wide-scale scanning of your internal and external environment to identify known flaws and missing patches before they're exploited.

List
02

Penetration Testing

Our senior engineers manually attempt to breach your defenses and move laterally through your network proving what a hacker could achieve today.

 

 

// Industries We Support //

Testing Tailored to Your Sector

We scope every assessment and penetration test to the compliance realities and threat models of the industries we serve.

List

Healthcare

HIPAA requires proof, not promises. Our assessments and pen tests protect patient records and clinical systems while satisfying auditors.

List

Financial Services

PCI-DSS compliance demands regular, documented testing. We validate payment systems and cardholder data environments against real attacker logic.

List

SMBs

Limited IT staff doesn't mean limited risk. We deliver enterprise-grade testing scaled to fit small and mid-sized budgets and teams.

List

Manufacturing

OT and IT convergence opens new attack paths. We validate industrial control systems and production networks without disrupting operations.

List

Education

Distributed campuses and research data create a wide attack surface. We help schools and universities validate defenses across every connected system.

List

Non-Profit

Donor data and lean security budgets are a risky mix. We help mission-driven organizations find gaps before attackers exploit trust.

// How We Work //

A Proven Process for Reliable Testing

Every testing engagement follows the same disciplined, transparent process — so you always know the next step and the reason behind it. It's the same proven approach featured across the STSG site.

We learn your business, your critical assets, and what a breach would cost you.

Assess

We scope the engagement and map your attack surface across every in-scope system.

Plan

We design a testing plan mapped to your risk, compliance needs, and rules of engagement.

Implement

We test with real attacker logic and document every finding with proof of concept.

Support

A vulnerability assessment is broad and automated — it continuously scans your environment to find known flaws and missing patches. A penetration test is deep and manual — our engineers actively exploit weaknesses to prove what an attacker could actually achieve. Most organizations need both: breadth to catch everything, depth to prove real impact.

Vulnerability assessment should be continuous, because new flaws appear daily and your environment changes constantly. Penetration testing is typically done at least annually and after any major change — plus whenever a compliance framework like PCI-DSS requires it.

No. We scope every engagement with clear rules of engagement and, where needed, test non-disruptively or in off-hours. For sensitive environments like manufacturing OT, we validate systems without interrupting production.

Not just a list of problems — a prioritized, evidence-based roadmap. Every finding is backed by proof-of-concept and ranked by real business risk, so your team and budget go straight to what matters most.
