Threat Detection & Response – Incident Response, Forensics, external attack

From Detection to Elimination: Proactive, Strategic Defense

Detection is the beginning, not the end. The most damaging attacks today use legitimate system tools to avoid tripping alerts, living quietly inside an environment for weeks. STSG’s Threat Detection & Response practice takes an offensive posture — hunting adversaries, mapping your attack surface, and responding with surgical precision.

//WHY IT MATTERS //

The STSG Security Advantage:
We Watch the Clock.
You Run the Company.

Most providers alert you to a problem and leave the cleanup to you. We deliver outcomes — around-the-clock human oversight, decisive action, and one partner for your entire security stack.

List

24/7 Human Oversight

Not just automated alerts. Real analysts watch your environment around the clock, filtering the noise to surface the threats that actually matter.

List

Results, Not Reports

Most providers notify you of a problem and leave the cleanup to you. We act — containing, eliminating, and hardening — so you get outcomes, not just tickets.

List

One Partner, Full Stack

SOC, MDR, and incident response under one roof. Measurable reductions in detection and containment time, plus a documented compliance posture.

// 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.

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.

What's Included in
Threat Detection & Response

Rapid incident response, courtroom-grade forensics, continuous attack-surface mapping, and intelligence-led hunting — combined so you don't just spot threats, you eliminate them.

List
01

24/7 Managed Incident Response

The first sixty minutes of a confirmed breach matter most. We act immediately — isolating segments, revoking credentials, and terminating malicious processes — then remove persistence and deliver a hardening roadmap.

List
02

Digital Forensics & Root Cause Analysis

Preventing the next breach means understanding this one. Our specialists reconstruct the full attacker timeline, with chain-of-custody standards admissible for legal and insurance proceedings.

List
03

External Attack Surface Management (EASM)

Most breaches begin at the edge — forgotten assets, misconfigured cloud storage, unmonitored services. We continuously map your external footprint and rank findings by real-world exploit activity.

List
04

Proactive Threat Hunting

Attackers can hide inside a network for months. Our analysts run scheduled, hypothesis-driven hunts using the MITRE ATT&CK framework, informed by global threat feeds.

 

 

// Industries We Support //

Security Validated
for Your Sector

We tailor monitoring, testing, and response 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 Security

Every managed security 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.

Discover

We learn your business, your critical assets, and the threats most likely to target you.

Assess

We run a security gap analysis, mapping your exposure and current detection coverage.

Plan

We design a managed security program mapped to your risk, compliance, and budget.

Implement

We deploy SOC monitoring and response, then tune detections against your environment.

The first sixty minutes are the most consequential. We act immediately — isolating affected segments, revoking compromised credentials, and terminating malicious processes — then move to full cleanup, removing backdoors and persistence and delivering a hardening roadmap.

Because the most damaging attacks use legitimate system tools to avoid triggering alerts, and can live inside a network for months. Our analysts run hypothesis-driven hunts with the MITRE ATT&CK framework to find adversaries that signature-based detection misses entirely.

EASM continuously maps everything an attacker can see from the outside — forgotten assets, misconfigured cloud storage, unmonitored services. We rank what we find by real-world exploit activity so you close the most dangerous gaps first.

Yes. Our specialists reconstruct the complete attacker timeline and maintain findings to rigorous chain-of-custody standards, so they're admissible for legal and insurance proceedings.
