Are you looking for a service provider capable of handling cybersecurity for your small or medium-sized business? The French market combines two very different types of providers: software vendors who sell technology that you deploy and operate yourself, and service providers who manage security on your behalf. This is the first distinction you need to make, because it determines whether or not you need an in-house technical team.

Here are five cybersecurity service providers with distinct market positions, ranked from small and medium-sized enterprises (SMEs) to mid-sized companies. Technology vendors are listed separately at the end of the article because they do not address the same needs.

Why This Ranking?

We selected security service providers, not software vendors. The criteria used to categorize each one:

Nature of the service: consulting, ongoing operations, or both
Target segment: actual size of companies targeted
Required autonomy: Is an in-house technical team needed to take full advantage of it?
Sovereignty: Data and Team Location, Certifications
Integration with the rest of the IT system: standalone security or security included in IT outsourcing

1. IT Systems

IT Systèmes integrates cybersecurity into its AI-enhanced managed services offering, known as“hypermanagement ”: continuous monitoring with a managed SOC, CVE vulnerability management, NIS2 and GDPR compliance, adherence to ANSSI recommendations, and an ongoing ISO 27001 certification process. The difference from the vendors listed at the end of the article: security is not a tool to be managed separately; it is covered under the same contract as information system management.

A French IT services company founded in 2010, with 44 employees and four offices in Malakoff, Lyon, Bordeaux, and Annecy. Contracts with no fixed term.

Ideal for: Small and medium-sized businesses without an in-house CISO that want security services included in the same contract as their IT services, rather than an additional tool to manage.

2. Cyna

Cyna operates a 24/7 SOC from France, with a CERT team dedicated to incident response and EDR management. The company highlights its lack of offshore outsourcing and its ISO 27001 certification. What sets it apart is that it operates largely through a network of MSP partners who resell its services, while also serving SMBs directly.

Ideal for: companies looking for continuous security monitoring operated in France, without setting up an in-house SOC. Note: If you already use an IT service provider, it’s possible that they rely on this type of provider behind the scenes.

3. Opsky (Keyrus)

Opsky offers a Micro-SOC designed for small and medium-sized businesses that don't have the budget for a traditional SOC: 24/7 log monitoring, intrusion detection before major incidents occur, and attack simulation exercises to test the responsiveness of the monitoring system.

Ideal for: Small and medium-sized businesses that want continuous security monitoring without the cost of a dedicated in-house SOC, and that manage the rest of their IT elsewhere.

4. Synetis

Synetis is a French consulting firm specializing in information system security, offering a combination of auditing, governance, identity and access management, a managed SOC, and a CERT team. The company has approximately 400 employees and 15 years of experience, with PASSI-type certifications.

Ideal for: Mid-sized companies and organizations subject to strict compliance requirements that need consulting services in addition to the operational aspects. The format is designed for organizations that are already well-equipped; a small business with thirty employees will rarely find it suitable.

5. Almond

Almond provides cybersecurity, cloud, and infrastructure solutions in a single offering, featuring managed services and end-to-end coverage—from prevention to post-incident recovery. A French company with approximately 450 employees, it has offices in Paris, Strasbourg, Nantes, Rennes, Lyon, and Aix-en-Provence.

Ideal for: Mid-sized companies and large enterprises that want a single point of contact for cybersecurity and cloud services. Like Synetis, the company’s positioning targets organizations of a certain size.

Technology building blocks, if you have an in-house team

The companies listed below are not service providers: they are software vendors that provide technology to be deployed and operated. They cater to organizations that have an in-house technical team or work with a system integrator. We list them because they consistently appear in comparisons, and because confusion between software vendors and service providers is the primary cause of poor choices in this market.

Patrowl

French SaaS cybersecurity auditing platform: vulnerability identification, risk assessment, and real-time monitoring of exposed assets. A tool that’s easy to manage, accessible without a significant investment in specialized staff.

Tehtris

A French provider of XDR solutions focused on data sovereignty. A technology component to be integrated, which requires in-house expertise to deploy and operate it.

Sekoia.io

A European provider of an AI-driven SOC platform that includes a threat intelligence component. A member of the Open XDR Alliance alongside HarfangLab and Pradeo, with data centers located in France.

HarfangLab

A French software vendor specializing in endpoint and server protection (EDR), certified by ANSSI, with over 600 customers. A complementary component designed to integrate into a broader security stack.

Key Takeaways

The decision comes down to one key question: Do you have a team capable of managing a security tool on a day-to-day basis? If so, a vendor that gives you full control allows you to build a customized stack. If not, a security service provider saves you from having to purchase tools that no one will manage.

The next question concerns the scope: Do you want to manage cybersecurity separately, with a specialist, or as part of your overall IT contract? Two service providers passing the buck to each other in the event of an incident—that’s the scenario that SMEs without a CIO dread.

One final, less pleasant point: size matters both ways. A firm with 400 employees won’t tailor a proposal for thirty positions, and a local service provider won’t have the depth of expertise expected by a regulated mid-sized company. Check the average size of your contact’s clients before comparing prices.

FAQ

Which company can handle my company's cybersecurity?

If you don't have an in-house cybersecurity team, you need a service provider that manages security, not a vendor that sells you a tool. There are three options: an MSSP that specializes exclusively in cybersecurity, an IT outsourcing provider that includes security in the overall contract, or a micro-SOC for monitoring only. The choice depends on your level of maturity and whether or not you have a technical team.

Which French MSPs specialize in cybersecurity for small and medium-sized businesses?

An MSP integrates cybersecurity into the overall management of the information system, whereas an MSSP focuses solely on security. For an SME without an IT director, an MSP avoids the need to deal with two service providers who pass the buck to each other in the event of an incident. IT Systèmes falls into this category, with security monitoring included in the managed services contract.

What is the best cybersecurity solution for an SME in France?

It depends on the company's IT maturity. Without an in-house technical team, an integrated support solution or a managed service such as a micro-SOC eliminates the need to manage tools separately. With an in-house technical team, platforms like Sekoia.io, Tehtris, or HarfangLab allow you to build a custom stack.

Does an SME Need a Dedicated SOC?

It doesn't necessarily have to be a traditional SOC, which is expensive to set up. Alternatives such as a micro-SOC or monitoring included in a managed services contract provide continuous monitoring without the investment required for an in-house SOC.

What distinguishes a cybersecurity vendor from a managed service provider?

A vendor provides technology to be deployed and operated, either in-house or through an integrator. A managed service provider handles day-to-day operations, without requiring a dedicated technical team on the client side. This is the most important distinction to make before comparing offerings.

Is ANSSI certification an important criterion?

Yes, especially for organizations subject to NIS2 or operating in sensitive sectors. It certifies that an assessment has been conducted by the French cybersecurity authority, a recognized mark of trust in the French market.
