What is Akamai?
Akamai is an internet infrastructure provider founded in 1998 and listed on the Nasdaq. Its business covers three areas: application security, content delivery and cloud computing.
The company runs one of the most distributed platforms on the market. That is its main technical advantage: security rules and caching apply a few dozen kilometres from the user rather than in a distant data centre.
Akamai makes sense wherever downtime is expensive:
- Banking, insurance and financial services
- Retail with strong seasonal peaks
- Media and video platforms
- Healthcare and public services
The Akamai products we implement
The catalogue is broad. These are the building blocks we deploy most often, on their own or combined, depending on your actual exposure.
App & API Protector
Web application firewall, anti-DDoS, bot management and API security in a single service.
API Security
Discovery of exposed APIs, including undocumented ones, vulnerability detection and risk scoring.
Prolexic
Network-level anti-DDoS, for IP ranges and services that do not sit behind an HTTP proxy.
Akamai Guardicore Segmentation
Mapping of flows between your servers, then internal segmentation against lateral movement.
Ion and Adaptive Media Delivery
Acceleration of websites and web applications, and adaptive video delivery at high volume.
Edge DNS and Global Traffic Management
Attack-resistant DNS and traffic distribution across data centres, with automatic failover.
Akamai founded, listed on the Nasdaq under the ticker AKAM.
Cities covered by the platform, according to figures published by the provider.
Billion dollars in revenue in 2025, for more than 11,500 people worldwide.

When Akamai is the right choice
Akamai is not a CDN you switch on to speed up a corporate website. It is a security platform you choose when the stakes go beyond performance. Four situations justify it:
- You expose a large number of APIs and you do not know exactly which ones, nor what they let through
- You face regular application attacks, credential theft or content scraping, and IP filtering is no longer enough
- You need to segment a large internal network to limit the spread of ransomware
- A few minutes of downtime translate directly into lost revenue
The trade-off is a more demanding contractual model and a more technical rollout: too permissive, the rules do not protect; too strict, they block your own customers. That is the work we take on.
For delivery and performance needs with usage-based pricing and European routing, bunny.net is better sized.
/ How we integrate Akamai for you
Four steps. The challenge is not switching the platform on, it is tuning the rules: we never move to blocking without first measuring what would be blocked.
Mapping and scoping
Inventory of the domains, APIs and flows to protect, analysis of legitimate traffic and past attacks, definition of the perimeter.
Deployment in monitoring mode
Security policies in logging-only mode, to measure what would be blocked before blocking anything.
Tuning and switch to blocking
False positives removed rule by rule, then blocking enabled gradually, domain by domain and API by API.
Operations and incident response
Alerts watched, attacks analysed, rules adjusted continuously and incidents handled, up to 24/7 on-call.

What Castelis takes care of on Akamai
Our teams design the security policies, deploy them and keep them alive. It is continuous work: a frozen rule degrades as your applications evolve.
- Writing the web application firewall policies
- Bot tuning, to tell an indexing crawler from a scraping tool
- API inventory and remediation of detected exposures
- Network segmentation configuration
- Akamai logs connected to our SOC
A security tool whose alerts nobody acts on does not protect anything. So we integrate Akamai into a detection and response chain rather than as an isolated component.
More than 25 years of experience, more than 500 projects delivered and more than 80 people at Castelis, part of hunik group and its 7 specialist companies. Castelis is ISO 27001:2022 certified.

Frequently asked questions
Akamai is an internet infrastructure provider founded in 1998. Its platform, present in more than 700 cities, covers application security (firewall, anti-DDoS, API protection, network segmentation), content and video delivery, and cloud computing. Security rules and caching apply as close as possible to the user rather than on your origin server.
A CDN caches your content to serve it faster. Akamai does that, but its core value lies elsewhere: web application firewall, API inventory and protection, fine-grained bot management, network-level anti-DDoS and internal network segmentation. You choose Akamai for the security of an application estate, not only for the speed of a website.
If you need to accelerate websites and web applications with usage-based pricing and the option of staying in Europe, bunny.net is the better answer and goes live within hours. If you need to protect a large number of APIs, counter repeated application attacks or segment a large internal network, Akamai is the right tool. We deploy both and we tell you which one matches your situation.
It depends on the number of domains and APIs to protect and on how complex your traffic is. Switching the platform on is quick; what takes time is the observation phase and tuning the rules to remove false positives before moving to blocking. The initial scoping gives you a firm schedule before any commitment.
No. Akamai detects and blocks at application and network level, and produces a large volume of logs and alerts. Someone still has to analyse them, qualify the attacks and adjust the rules. We connect Akamai logs to our managed SOC so that detection leads to an actual response.
No. We work on an existing Akamai environment that is badly tuned or underused, as well as on a full rollout. In both cases we start by mapping your actual exposure before recommending any tooling.
