Cybersecurity with Microsoft: prevent, detect and respond automatically.
Arcetec is a Microsoft Partner and implements Microsoft security end to end: multicloud posture with Microsoft Defender for Cloud, detection and response with Microsoft Sentinel and automated playbooks, and identity and access governed with Microsoft Entra ID. The goal is for prevention, detection and response to stop depending on someone watching a screen: security operations live in a single portal, playbooks are generated in natural language, and response is orchestrated automatically with a trail of every action — isolating, revoking and notifying happen in the moment, and the analysis is left for the morning. The first reference is the company itself: Arcetec's corporate panel is protected with Entra ID and a second factor implemented by the same team that offers the service. Defender and Sentinel are turned on over the tenant the company already has, with no additional platforms; Arcetec's job is to harden the posture, deploy detection with custom playbooks, prevent intrusions and leave orchestrated response in place, along with the identity and access lifecycle. Engagements start with a conversation and a scoped assessment, with fixed scope and price, and the pilot is measured in weeks. We operate from Cajicá, Cundinamarca.
Posture with Defender for Cloud, detection and response with Sentinel, identity with Entra ID. Your operation's security stops depending on someone watching the screen.
- Response orchestrates itself, with a trail of every action
- Turned on over the tenant you already have
- Our own panel is protected with the same tools we sell
Panel de Microsoft Sentinel con los incidentes de seguridad del día, cada uno con su severidad, y un playbook de respuesta automática ya en ejecución: la sesión se revoca y el segundo factor se exige sin que nadie tenga que despertarse.
Cybersecurity with Microsoft: what you'll find.
What this pillar covers, stated up front.
- Multicloud posture with Defender — Defender for Cloud measures and hardens the posture of what runs in Azure and other clouds, with priorities instead of an endless list.
- Detection with automated playbooks — Sentinel correlates signals from across the tenant and playbooks respond in the moment, not when someone opens their email.
- Identity governed with Entra ID — Second factor, conditional access and a lifecycle in which access ends when the relationship ends.
- Orchestrated, hands-free response — Isolating the device, revoking the session and notifying the person in charge happen automatically, with a trail of every action.
Defender and Sentinel: unified SecOps, out of the box.
What Microsoft's security platform already includes; we turn it on over your tenant.
- 1 — single portal: security operations live in Defender
- GA — Sentinel data lake: the SIEM for the agentic era
- SOAR — playbooks generated in natural language
- MCP — even Sentinel exposes its own MCP server
Cybersecurity services: what Arcetec does.
The platform brings the controls. Turning them on in the right order, writing the playbooks for your scenarios and leaving the response in place is the work.
- Hardening with Defender for Cloud — Your posture measured and prioritized across what runs in your clouds, and the plan to raise it without slowing down operations.
- Sentinel deployment with custom playbooks — Your tenant's signals correlated and playbooks written for your scenarios, not a template's.
- Intrusion prevention and orchestration — Isolate, revoke and notify automatically when something happens, with a complete trail of what the response did and when.
- Identity and access with Entra ID — Second factor, conditional access and the complete lifecycle: access is created when someone joins and ends when they leave.
We sell what we use
The first reference is ourselves.
- Our own panel — Arcetec's corporate panel is protected with Entra ID and MFA implemented by us. The first reference is ourselves.
- Azure and information security — The same layered approach —identity, encryption, private network, detection and backup— applied to infrastructure, with paths by industry.

Who responds if something happens at two in the morning?
If the answer is “someone will see it the next day,” that's the conversation to have. With orchestrated response, isolating, revoking and notifying happen in the moment — and the analysis is left for the morning.
