Security — Cyber Security
Detection that gets investigated. Architecture that survives a red team. Compliance evidence produced continuously. We run security programs end to end — SOC, SIEM engineering, cloud and identity hardening, OT-aware controls, and zero-trust adoption that doesn't break uptime.
On-call rotation with incident response and post-incident reviews.
Tuned content. High-signal alerts. No more "everything is critical."
Plant-floor segmentation and monitoring without breaking safety interlocks.
Controls mapped to telemetry. Audit packs produced monthly, not annually.
The honest version
Most security programs accumulate tools faster than they accumulate operators. Alerts age in queues. Backups exist but restores fail in drills. OT environments get carpet-bombed with IT controls that break safety. We focus on the operational gaps — not selling another SKU.
01 — DETECTION
Detection engineering tuned to your stack, your assets, and your real adversary paths. High-signal content your tier-one can action without escalation soup. Tuning cadence baked into operations.
02 — ARCHITECTURE
Identity hygiene, segmentation, phishing resistance, and patch defensibility addressed in the order that compounds. Security controls are prioritized by their ability to reduce real operational risk, strengthen resilience, and produce measurable improvements across the environment.
03 — EVIDENCE
Policies tied to controls. Controls tied to telemetry. Evidence packs your GRC team can run monthly — not scavenger hunts in the two weeks before an audit visit.
Why intSignal
Organizations need more than cybersecurity tools. They need security strategies that align with their operations, infrastructure, compliance requirements, and business objectives.
intSignal delivers cybersecurity, cloud, networking, telecommunications, and IT expertise through a unified approach. Our team works directly with clients to design, implement, and support solutions tailored to their environment, helping reduce complexity, improve visibility, and strengthen security across the organization.
By combining deep technical expertise with a practical understanding of business operations, intSignal helps organizations make faster decisions, simplify vendor management, and build resilient technology environments that support long-term growth.
Four pillars of coverage
One narrative, four operational areas. Each pillar maps to specific services — pick the depth you need, sequence the rest, no vendor-lock pressure.
INVESTIGATION · CONTAINMENT · METRICS
The Security Operations Center is where alerts become decisions. We staff investigation discipline, hunt cadence, and containment paths scoped to the assets your business actually names — not generic Tier 1/2/3 templates that hand off forever.
Playbooks reference your ticketing system, your legal hold workflow, and your crisis comms. Metrics leadership can read without an acronym key. Tabletops surface the RACI gaps that matter before an incident does.
CONTROLS · BASELINES · EVIDENCE
Security controls maintained like infrastructure. Patch defensibility, baseline drift, and exposure management sequenced with change windows your application teams can actually tolerate — not "deploy this critical fix tonight" theater.
Exceptions get owners and expiration dates. Evidence is suitable for ISO and SOC cadence. Coordination happens through your ITSM system, not shadow spreadsheets the auditor finds during fieldwork.
SAAS · IAM · ZERO TRUST
The attack surface that's grown the fastest. SaaS posture, IAM blast radius, and cloud workload protection treated as systems engineering — with rollback thinking, not just maturity-score chasing.
Zero trust initiatives are prioritized according to measurable risk reduction and operational value. Conditional access, device trust, and segmentation controls are implemented through a phased approach that balances security improvements with usability, performance, and long term maintainability.
ICS · SCADA · UPTIME · SAFETY
Segmentation, monitoring, and response models that respect uptime and physical safety constraints. Not generic IT playbooks pasted onto a plant floor with the protocol filters disabled because "they were causing issues."
Maintenance windows are honored in design. Engineering access into industrial control environments stays auditable. Evidence boards can reconcile with production reality — not just the network diagram from three years ago.

How engagements run
Security programs that try to fix everything at once fail predictably. We baseline first, sequence by risk reduction, then operate the run state with metrics your leadership can interpret.
PHASE 01 · WEEKS 1–4
We map current detective and preventive coverage against the attack paths your industry actually sees — not generic maturity matrices divorced from your stack. The output is a prioritized gap list with effort and impact, not a 200-page deck.
PHASE 02 · WEEKS 4–16
Foundational improvements begin with credential security, visibility gaps, phishing resilience, and access controls. Broader initiatives such as segmentation, privileged access modernization, and detection engineering follow through a phased roadmap that delivers measurable value at every stage.
PHASE 03 · ONGOING
Run-state operations: tabletop cadence, tuning cycles, threat hunts, and metrics your board can interpret without an acronym key. Quarterly reviews tie coverage gains to spend so the next budget conversation has evidence.
Detection, engineering, and governance mapped to email, cloud, network, OT, and identity realities.
We deliver threat-facing programs: SOC and incident response workflows, SIEM engineering tuned to high-signal detection, modern email and cloud workload protections, network segmentation, insider investigations, OT-aware controls, managed surveillance where appropriate, and zero-trust adoption phased for culture—not slogans.
Compliance evidence is produced continuously—policies tied to controls and telemetry your auditors can trace.
INCIDENT
Detection content fired, but nobody triaged it in time. The root cause was visibility plus capacity, not the missing tool the vendor is now pitching.
REGULATOR
Renewal questionnaire surfaced gaps. Cyber insurance carrier is asking for evidence you don't currently produce on a cadence.
OT
Plant managers are right to push back. IT controls applied without protocol awareness break safety interlocks. You need a real OT plan.
MANDATE
The strategic direction is real, the funding signal is not. Engagement starts with the sequencing question: what actually reduces risk first.
SPRAWL
Two SIEMs, three EDRs, and a SOAR nobody finished onboarding. Procurement wants rationalization. Analysts want fewer panes of glass.
FORENSICS
An HR or legal-led investigation needs evidence collection, chain of custody, and a narrative that holds up. Not a slack thread of suspicions.
Hardening and operating practices aligned to the frameworks your assessors recognize. intSignal is not the certified entity for most of these — we deliver the controls and evidence that make your audit possible.
CIS
Prioritized remediation, defensible exceptions.
SOC 2
Evidence cadence ready for audit fieldwork.
ISO
ISMS and cloud-services controls.
HIPAA
Safeguards mapped to PHI flows. BAA via partner.
SECTOR
Industry-specific scoping where required.
PRIVACY
Operational privacy controls and reporting.
FAQ
If yours isn't here, ask in the consultation. We'd rather flag the awkward bits early than find them during an incident.
Both models are supported. Fully managed when you don't have an in-house team. Co-managed when you do — we operate specific functions (SOC nights/weekends, detection engineering, threat hunting) while your team owns the rest. We'll be honest about which model fits your maturity and headcount before scoping.
Yes. Tool replacement is rarely the right first move. We integrate with Splunk, Sentinel, Elastic, CrowdStrike, SentinelOne, Defender, the major cloud-native security stacks, and most ticketing systems. Migration happens only when the current tool actively blocks a higher-priority outcome — not for vendor reasons.
Acknowledgement targets are measured in minutes. Investigation, containment, and resolution targets are scoped per engagement based on severity tiers you define with us — because "P1" doesn't mean the same thing at every customer. Specific numbers are part of the contract and backed by credits when missed.
Most engagements are monthly recurring based on scope — number of endpoints, log volume, SOC tier, and which services you include. Project work (compliance assessments, architecture reviews, zero-trust roadmaps) is fixed-price. We'll model the cost against your environment before you commit, with no auto-escalation clauses.
OT engagements never start with installing agents. We start by understanding the protocols, the safety interlocks, the maintenance window calendar, and the engineering access patterns. Monitoring is passive where possible. Active controls only land after the plant team signs off on the change. Generic IT playbooks don't apply.
That's the bar. Evidence packs map directly to control statements with timestamps, source telemetry, and a defensible chain of custody. We work with the audit firms you'd recognize, so the format and depth are what they expect. If something won't survive fieldwork, we'd rather know now than during the report-writing call.
The questionnaire keeps getting longer. We help align the program to common carrier requirements (MFA on privileged accounts, EDR coverage, immutable backups, IR retainer in place, patching cadence) and produce evidence in the format carriers and brokers actually accept. The goal is renewal at a price that makes sense — not policy theater.
Tell us where the challenges exist, whether in operations, compliance, OT environments, identity, or security governance. We'll provide a practical roadmap, operating model, and implementation strategy aligned to your business objectives and risk priorities.
