The Best DDoS Protection Services
UPDATED: July 11, 2024
DDoS attacks are evolving— they are becoming more sophisticated and distributed. Now, they are starting to give real headaches to cyber-security experts.
Since the DDoS focus changed from network and transport layers (L3 and L4) to the application layer (L7), DDoS attacks are more challenging to mitigate. The volume of these attacks is also getting out of control. DDoS sources or bots are now distributed to every corner of the earth and into anything connected to the Internet. If something has IP, like cameras, NAS, servers, mobiles, or IoT devices, it can be turned into a bot and commanded to attack.
Here is our list of the best DDoS Protection Services
- SolarWinds Security Event Manager – FREE TRIAL A SIEM solution that uses a multi-layer approach to monitor event logs from many sources, and detect and prevent DDoS activities. Get a 30-day free trial.
- ManageEngine Log360 – FREE TRIAL This large bundle of services is able to identify threats and implement automated responses. Available for Windows Server. Start 30-day free trial.
- Akamai Prolexic It uses Akamai’s massive CDN with scrubbing centers to identify and stop DDoS attacks in the cloud before they reach your assets.
- Sucuri Website Firewall A cloud-based WAF with strong protection from DDoS attacks. It filters, and blocks suspicious DDoS traffic with intelligence and GeoIP detection.
- Cloudflare One of the largest CDN providers that offer protection against 3,4, and 7 layer DDoS attacks at a maximum capacity of 37 Tbps.
- Akamai App and API Protector A WAF built on top of Akamai Intelligent Edge Platform and designed to protect web assets from large DDoS attacks.
- CloudBric’s SWAP A fully-managed web security service with a cloud-based WAF based on artificial intelligence. The Cloudbric SWAP offers protection from Layer 3, 4, and 7 DDoS attacks
So, what can a DDOS protection service do to protect you from a DDoS attack?
- Content Delivery Networks (CDNs) are a great defense against DDoS attacks because they redistribute traffic to edge servers. They eliminate the single point of failure by helping the victim (server) process traffic. CDNs can use DNS or Anycast technology.
- Web Application Firewall (WAF) uses a set of rules, blacklists, or whitelists to filter traffic. Most WAFs use behavior-based rules to measure stress (DDoS attack) against a baseline of “ordinary traffic”.
- DDoS protection mechanisms might also include rate limiting, a dashboard to manage traffic, threat intelligence databases, and managed services with support.
Our methodology for selecting DDoS protection services
We reviewed the market for encrypted DDoS protection systems and analyzed the options based on the following criteria:
- Edge services that filter all traffic on the way to the Web server
- Plans that are suitable for small businesses and others that can protect companies that frequently get attacked by very large attack campaigns
- A platform that provides additional services, such as a content delivery network
- An alert for a detected live attack
- Attack analysis facilities
- A free trial, a demo, or a free plan that enables the service to be validated without paying
- Value for money from a DDoS protection system that is able to absorb very large amounts of traffic without costing too much
With these selection criteria in mind, we explored the market to identify DDoS protection services that can protect against traffic floods and we made sure to include some on-premises options for companies that don’t like using cloud-based systems.
The best DDoS Protection Service
1. SolarWinds Security Event Manager – FREE TRIAL
SolarWinds Security Event Manager (SEM) is a Security Information and Event Management (SIEM) software, that provides real-time analysis of security alerts generated by the network or applications. SolarWinds SEM (formerly Log & Event Manager) is capable of monitoring event logs from many sources and identifying DDoS attacks.
Key Features:
- Automated threat detection and response: This is a SIEM service
- Forensics analysis: Based on log messages
- Cyber threat intelligence: Warns of attack campaigns
- Compliance reporting: For HIPAA, PCI DSS, and SOX
- Attack categorization: Identifies when attacks against the network have started
Why do we recommend it?
While not being a full DDoS protection system, the SolarWinds Security Event Manager can identify DDoS traffic floods and raise an alert. Set up automated responses to manipulate access to the network’s gateway to complete the picture. This package provides detection for a wide range of security threats, not just DDoS attacks.
How can SolarWinds Security Event Manager protect you from DDoS?
SolarWinds SEM uses cyber-threat intelligence sourced from open communities to help identify and block blacklisted IPs. It attempts to go for the Botnet’s Command & Control Center using logs from a wide range of sources.
Who is it recommended for?
This is a good choice for companies that aren’t interested in remote services and want to host all of their security systems themselves. It is a solution for large businesses. As this is a detection service rather than a DDoS absorption tool, companies using the package will need to have other mechanisms in place to respond to attacks.
Pros:
- Enterprise-Focused SIEM: Has a wide range of integrations
- Automated Log Scanning: Also facilities for manual searches
- On-Premises Software: For those who don’t trust cloud systems
- Historical Analysis Tool: Provides attack intelligence after the event
- Log Manager: Collects, consolidates, and files log messages from many sources
Cons:
- No SaaS Option: This package is only available for on-premises hosting on Windows Server
Price: The perpetual license starts at $5,093 and the subscription starts at $2,613. Register to Security Event Manager for a fully-functional 30-day free trial.
EDITOR'S CHOICE
SolarWinds Security Event Manager is our top pick for a DDoS protection service because it isn’t limited to detecting traffic flood attacks. This system will look for all types of threats, which include both manual and automated attacks. The package will look at the possibility of an account takeover, an insider threat, or an intruder – all of which are attacks that happen within the network and wouldn’t be detected by a remote edge service. The service will also identify external attacks and implement automated remediation.

Key Features:
- Activity Tracking: Looks for known patterns of malicious behavior
- Alerts for Unusual Activity: Will detect insider threats, intrusion, and automated attacks
- Threat Intelligence Feed: Provides information on current attack campaigns
- Automated Responses: Shuts down threats
Why do we recommend it?
ManageEngine Log360 is a major rival to the SolarWinds system on this list. It is a general threat detection system that operates search on log messages and network activity feeds. The service will identify a range of threats, both manual and automated. DDoS is just one of the automated attack strategies that this package can identify.
How can ManageEngine Log360 protect against DDoS attacks?
The SIEM gets a threat intelligence feed, which includes a blacklist of IP addresses that are known sources of malicious activity. This will include the addresses of infected zombie sources in botnets and well-known sources for reflection attacks. The system can load this block list into your third-party firewall and reject all malicious traffic.
Who is it recommended for?
This is a solution for large businesses. It is a superpack of several ManageEngine modules – many of which have free editions for small businesses, while Log360 does not. Small companies should look at the components of the Log360 system and work out whether they would get a better deal just buying those elements that they really need.
Pros:
- Security Orchestration, Automation, and Response (SOAR): Pulls in the services of third-party security systems
- Alerts can be Channeled to Ticketing Services: ManageEngine ServiceDesk Plus
- Network and Host Threat Detection: Based on log messages and network activity feeds
- Compliance Reporting: For PCI DSS, GDPR, FISMA, HIPAA, SOX, and GLBA.
Cons:
- Large Bundle of Tools and not Suitable for Small Businesses: SMEs should look at the other modules available for ManageEngine

The company is also recommended for its DNS management services.
What Cloudflare does to protect you from DDoS attacks? Since it is very likely that traffic going to your web app or site is running through CloudFlare’s network, it will catch it upstream before it hits your server. It can identify DDoS attacks and other botnet-generated traffic like data scraping, or spamming comments.
Who is it recommended for?
Cloudflare has made its services accessible to all businesses and partners with web hosting providers around the world to provide a free entry-level package of web protection services to new website owners. The company also has a long list of very large multinationals in its client base.

Cloudbric’s WAF uses Smart Web Application Protection (SWAP), which is Cloudbric’s patented mechanism that employs AI (pattern matching, semantics, and heuristic analysis) and a set of rulesets to identify and stop attacks.
Who is it recommended for?
The WAAP will interest any business that runs websites. As it is a proxy service, it doesn’t matter whether you host your website yourself or on a hosting service, it will protect the site. It can also protect multiple sites within one account and they can be hosted in different locations.
Pros:
- Fully Managed DDoS Service: Great for hands-off protection
- Integrates with Third-Party CDNs: Cloudbric does not offer CDN
- Provides Complete Protection: Scans across multiple network layers

Conclusion
The best strategy against DDoS attacks is to prepare beforehand. A successful DDoS attack can damage an entire business’s revenue, reputation, and productivity. Waiting until you are under attack and then look for help, is not a good solution.
Although a DDoS protection service will not stop the attack— it will mitigate it. It will make it less hostile so that your server can still respond to legitimate traffic— until the DDoS attacker runs out of resources.
To protect your IT infrastructure, on-premises tools like SolarWinds Security Event Manager or Akamai Prolexic Routed will do a great job. For distributed web apps, use a combination of large CDNs with intelligent WAFs. Akamai and Cloudflare have the largest CDNs+WAF. But Sucuri WAF and IndusFace AppTrana have intelligent filtering systems.
