AMOA SOC: building an SOC to meet your cybersecurity challenges

The SOC, your organization's cybersecurity control tower

The SOC is a dedicated team (in-house, outsourced or hybrid) that continuously monitors your information system to :

  • Detect threats (intrusions, attacks, abnormal behavior…),
  • Analyze security incidents,
  • React quickly to limit impacts (or even counter attacks in real time),
  • Prevent future attacks through continuous improvement.

Our internal, external or hybrid SOC project management offer: consulting, structuring and management.

A pragmatic, tailor-made approach.

Our cyber and SOC experts will support you in defining, scoping, choosing the tools, the service provider (in the case of outsourcing) and deploying your security operations center.

Strategic framing and expression of needs

  • Analysis of the cyber context (IS, threats, regulatory obligations, maturity...)
  • Clarification of SOC objectives (24/7 detection? compliance? anticipation? response? )
  • Identification of use cases to be covered (IT-oriented SOC? OT? cloud?)
  • Definition of functional scope (logs, SIEM, EDR, CMDB, tickets...)
  • Gathering of stakeholder expectations (CIO, CISO, production, business, COMEX)
01

Target model design

  • Choosing the model: in-house SOC, outsourced SOC, hybrid SOC
  • Defining service levels (SLAs), coverage schedules, roles and responsibilities (RACI)
  • Target architecture: log collection, SIEM, playbooks, supervision, ITSM interfacing
  • Governance: steering committee, alert management, reporting, crisis management
02

Help in choosing solutions or service providers

  • Drafting functional and technical specifications
  • Benchmarking and analyzing offers (SIEM, SOC-as-a-Service...)
  • Helping select MSSP provider if outsourcing
  • Negotiating and contracting
03

Steering the implementation project

  • Detailed planning, milestones, checkpoints
  • Monitoring the deployment of technical building blocks (collection, SIEM, alerting, tooling...)
  • Coordination of internal teams, integrator and/or MSSP (Managed Security Service Provider => provider of managed security services)
  • Change management (organization, tools, processes)
04

Production support

  • Implementation of alert handling procedures
  • Development of response playbooks
  • Support for internal teams (internal SOC or internal relays for MSSPs)
  • Monitoring of start-up in real conditions (run)
05

Structuring governance and continuous improvement

  • Definition of KPIs and reporting (number of alerts, response time, incidents avoided...)
  • Organization of steering committees (weekly, monthly)
  • Review of use case mapping
  • Progressive ramp-up of the SOC (prioritization by risks or critical assets)

Netsystem helped KERIALIS comply with DORA and implement its SOC

KERIALIS, a social protection institution dedicated to the legal and accounting professions, offers supplementary health, provident, long-term care, end-of-career and retirement benefits, as well as a range of services to support its policyholders on a day-to-day basis.

The organization wanted to improve its operational resilience by complying with DORA regulations, specific to its business sector and more generally to financial services companies.

"KERIALIS was looking for a service provider to help us comply with the DORA regulation. We chose Netsystem for their speed in getting in touch with us, the quality of their exchanges and the speed of their response. NETSYSTEM is an agile structure with a strong capacity to adapt, and experienced CISOs, particularly on the cybersecurity aspects linked to DORA."

Netsystem is PASSI qualified

PASSI qualification is issued by the French Information Systems Security Agency (ANSSI).

It is aimed at trusted service providers who carry out organizational and physical security audits, as well as audits of technical scopes, on their own behalf or on behalf of their customers.

It is a real guarantee of quality and expertise for organizations looking for a cybersecurity consultancy firm to carry out an audit of their structure.

Why choose Netsystem?

  • Independence from suppliers & MSSP
  • Experience in the field: SOC projects in sensitive contexts (OT, cloud, multisites…)
  • Integrated CISO expertise (steering cockpit, compliance, crisis management)
  • Long-term vision : an SOC aligned with your IS strategy and your business risks

As an independent firm, Netsystem can intervene:

  • Upstream to define the SOC strategy,
  • in project management to steer the project from A to Z,
  • in ongoing governance with an RSSI cockpit,
  • In one-off technical support (cloud, OT, IAM experts, etc.). ).

Implementing an effective SOC is not just about choosing a technical solution: it's above all about building a resilient organization, aligned with business risks and adapted to the reality on the ground. At Netsystem, we support our customers with a pragmatic, independent and results-oriented approach. We don't sell technological dreams; we work with them to build a detection and response system that is operational, sustainable and scalable. Each assignment is an opportunity for us to forge a strong bond with in-house teams: we co-construct the SOC with CISOs, CIOs and business managers, always keeping in mind a simple but demanding objective: to reinforce security, without burdening the organization. Our strength lies in the fact that we speak the language of the business, the regulators and the cyber operation. And that's what makes the difference when it comes to moving from strategy to action.

The main missions of a SOC
  • 24/7 monitoring of logs, networks, terminals, servers…
  • Anomaly detection via tools such as SIEM (Security Information and Event Management).
  • Alert processing and incident management.
  • Forensic analysis in the event of an incident (research into causes and impacts).
  • Continuous security improvement (feedback, reinforcement of defenses…).
What are the different levels of intervention?

Most SOCs adopt a hierarchical approach, comparable to the levels at which an incident is examined.

Three levels are often present within the SOC team:

  • Level 1: detection and qualification of alerts.
  • Level 2: advanced investigation, event correlation.
  • Level 3: incident response, advanced expertise, escalation to CISOs.
Why is an SOC important?

An SOC is essential to reduce the time needed to detect and respond to cyber-attacks. It allows us to centralize skills, improve responsiveness and ensure continuous monitoring in a context of constantly evolving threats.

What is a hybrid SOC?

A hybrid SOC is a mixed security center model, combining the strengths of an in-house SOC and an outsourced SOC (or one operated by an MSSP – Managed Security Service Provider). It’s an intelligent compromise for many organizations.

Principle of the hybrid SOC:

The idea is to keep governance and critical decisions in-house (steering, prioritization, crisis management…), while outsourcing technical building blocks such as 24/7 supervision, log collection, or certain analyses.

Why opt for a hybrid model?

  • Flexibility: resources tailored to needs (hours, volume, expertise…).
  • Control: the organization retains control over priorities and sensitive data.
  • Cost optimization: no need to internalize everything (very costly), or delegate everything (risk of loss of control).
  • Access to expertise: service providers bring experienced analysts and powerful tools.
  • Coverage 24/7: easier to guarantee with a partner.


Example of operation:

  • Level 1 (24/7 detection): provided by an MSSP provider.
  • Level 2 (analysis and correlation): shared between the partner and internal teams.
  • Level 3 (response, crisis, strategic decisions): managed in-house with the support of the CISO.

At Netsystem, this type of hybrid model can be offered to accompany the CISO cockpit: we structure governance and set up a detection/reaction ecosystem tailored to the challenges of each customer.
