French Hosting Provider I2SNETWORK: From a Satisfied Client to a Trusted Partner

In 2024, a French hosting company experienced firsthand the benefits of StormWall’s DDoS protection for its own network. The impact was so significant that they didn’t just continue using it—they became our official partner. Today, I2SNETWORK integrates StormWall’s advanced protection into its offerings, ensuring maximum security for its clients. Find out more in our success story.

Customer: I2SNETWORK

I2SNETWORK is one of France’s top hosting providers. Founded in February 2023, the company also operates under the EPYCORE brand.

I2SNETWORK offers web hosting, VPS, dedicated servers, and colocation services at its data centers in Vélizy-Villacoublay, serving both individuals and businesses. It also provides network transit through AS 52073, with options for physical interconnection or tunneling via GRE, EOIP, VXLAN, and L2TP.

Today, over 800 customers across industries such as gaming, retail, and software development rely on I2SNETWORK’s high-performance and resilient infrastructure. With a bandwidth capacity exceeding 100 Gbps, the company ensures fast, reliable connectivity with ultra-low latency.

Business Challenge: Ensuring Uninterrupted Service

For I2SNETWORK, network availability is a top priority. The company must guarantee seamless service for its clients and has already built a reputation as one of the most reliable hosting providers in France. To maintain this standard, I2SNETWORK continuously strengthens its network by adding new transit connections and expanding available routes to prevent downtime.

“Any network outage means significant financial losses for business clients—but even more importantly, it impacts the company’s reputation. This is especially critical—for example, for FiveM, where GTA V multiplayer servers operate in a highly competitive space. For these clients, consistent network uptime is essential”.

DDoS attacks remain one of the biggest risks to network stability. I2SNETWORK’s founders first experienced them in August 2021, during their previous project, SEAPERF. A DDoS attack took the network offline for over 24 hours, causing significant financial losses and reputational damage. As a result, the company saw a major decline in business activity.

However, that incident also became a turning point. It pushed the founders to invest in stronger DDoS protection for future projects and search for a reliable solution capable of defending a modern hosting provider’s network.

“Our biggest challenges today include complex Carpet Bombing, IP Spoofing, and high-power DDoS attacks. Since day one, we’ve been dealing with them almost daily,” says Louis Tressard, Shareholder at 𝅸𝅸I2SNETWORK.

Initially, they relied on manually blocking multiple IPs, but this approach proved inefficient and unsustainable. It was clear that a more sophisticated solution was needed.

Solution:  StormWall – The Key to Network Stability

To identify the best DDoS protection, I2SNETWORK tested multiple services. A two-week trial with StormWall delivered outstanding results, exceeding expectations across all key areas.

A key factor in choosing StormWall was its seamless compatibility with multiple transit providers, making integration effortless. Additionally, its flexible configuration options and user-friendly client portal further reinforced the decision.

After a month of real-world use, I2SNETWORK knew they had made the right choice. StormWall’s protection was both precise and highly effective, allowing the company to mitigate most attacks without even noticing them.

Deployment: Fast, Seamless Setup with Expert Support

I2SNETWORK deployed StormWall’s DDoS protection in May 2024, establishing a GRE tunnel between its PoP in Vélizy-Villacoublay and StormWall’s Frankfurt node. In February 2025, the company switched to a physical connection, keeping GRE only for backup.

“The setup was incredibly fast—we configured the tunnel and started announcing networks through StormWall in less than 24 hours. We encountered minor MTU and MSS issues, but their support team responded immediately, helping us resolve them without delays. They are also highly responsive via Telegram—most of the time, we get a reply in under 15 minutes, even outside business hours. We truly appreciate this level of service,” said representatives of the French hosting provider.

Partnership: A New Chapter in Collaboration

After four months, I2SNETWORK became a StormWall partner as more and more clients requested direct connections via GRE tunnels or contracts with StormWall for DDoS protection.

“DDoS protection is in high demand in the hosting industry since these attacks are among the most common. In fact, the first thing clients ask is: Are your services protected against DDoS attacks?”

Louis Tressard, Shareholder at 𝅸𝅸I2SNETWORK

Since partnering with StormWall, I2SNETWORK has received overwhelmingly positive feedback, especially from FiveM server operators, a key segment of its business. This partnership has not only enhanced service reliability but also strengthened the reputation of both companies.

Conclusion

I2SNETWORK is receiving more and more requests—not only from existing clients but also from potential customers—looking to sign direct contracts with StormWall. This partnership with a globally recognized anti-DDoS provider has become a key competitive advantage.

“Partnering with StormWall has been one of the biggest highlights of 2024. We’ve gained not only a reliable business partner but also a powerful DDoS protection solution with fast support and low latency. Network downtime and service disruptions are now minimal, giving us a strong edge over the competition. Our experience with StormWall is going very well, we’re very happy with their service, both in terms of the relationship and the service itself. Nothing to say, if you’re looking for protection, go to Stormwall “with closed eyes”, — says Léo Delsart.
