Connection methods

DNS connection

BGP connection

You can connect only one resource
One website/backend (can be on several IPs). Connecting additional resource = new connection
Cheaper and easier than BGP connection. Suitable for a small number of resources requiring protection.
Available for TCP traffic
(it will no longer work on UDP - for the businesses that have their own infrastructure: VPN, videoconferencing, IP telephony - and there is a need to transmit legitimate UDP traffic)
Does not require building a communication channel
(virtual or physical)
Suites for:
A business with a small amount of resources.
A business that does not have its own AS and infrastructure and a block of independent IP address providers.
A business that needs to cut down its expences by protecting only particular parts rather than the enire infrastructure
Ask an expert
You can connect the entire infrastructure with all its resources = AS (websites, mail, etc.) at once.
Connecting additional resources is free - client IP addresses are used
No need to change DNS records
Available for all traffic protocols
Video conferencing protection, telephony, VPN, mail server, etc.
Available for services that initiate outgoing connections
Requires mandatory construction of communication channels to increase fault tolerance and increase SLA
We can protect the entire infrastructure including communication channels - protection against channel overflow.
Traffic to the protected resource goes through trusted communication channels, which allows you to increase the level of service
Suites for:
A business that has a large number of resources
with 25 or more IP addresses = cheaper than connecting via DNS with a number of IP addresses of 25 or more (excluding channel costs)
A business that has its own AS and infrastructure and needs to protect video conferencing, telephony, VPN, and mail servers
A business that needs complete protection of it’s entire infrastructure

What is a DDoS attack?

A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming it with a flood of internet traffic. The attackers use multiple compromised computer systems as sources of attack traffic. By sending more network packets than the victim can process, the attacker can cause denial-of-service to legitimate users or systems. DDoS attacks are used to target websites, web applications, and other online services that rely on the availability of their services in order to function properly.

How does a DDoS attack work?

DDoS attacks involve interconnected networks of multiple machines to flood the server with a large amount of traffic, beyond its capacity. These networks comprise computers and various devices, including IoT devices, that have been compromised by malware, enabling remote control by malicious actors. These individual compromised devices are commonly referred to as bots or zombies, and a collection of these bots forms a botnet. 
 Once a botnet is established, the attacker gains the ability to orchestrate an attack by issuing remote commands to each bot within the network. 
 The botnet prompts each bot to send requests to the target's IP address. This barrage of requests has the potential to overwhelm the server or network, resulting in a denial-of-service situation for legitimate traffic.

What is DDoS protection?

DDoS mitigation encompasses the set of tools and techniques employed to safeguard networks and systems against DDoS attacks or minimize their detrimental effects. The process of successful DDoS mitigation means letting all incoming traffic pass through a scrubbing center where traffic is filtered using behavioral, heuristic and signature algorithms, and legitimate traffic is separated from malicious one permitting only user traffic reach the protected application.
 By implementing DDoS-specific protection organizations can effectively decrease their vulnerability to attacks, mitigating the risks associated with potential business disruptions and downtime. This proactive approach enables the defense mechanism to intercept and neutralize DDoS attacks while ensuring that legitimate visitors can continue accessing the company’s online services without interruption. DDoS protection acts as a barrier, preventing malicious traffic from reaching its intended target. As a result, the impact of the attack is significantly minimized, enabling uninterrupted business operations by allowing legitimate traffic to flow through as usual.

Who needs DDoS protection?

DDoS protection is especially important for organizations that rely on their online presence for business operations, as even a short period of downtime can result in significant financial losses. Organizations of all sizes - whether an SMB or a large corporation - can benefit from having a DDoS protection solution in place, as the cost of being unprepared far outweighs the cost of prevention. 

 DDoS mitigation services are especially demanded in such industries as finance, e-commerce, media, education, tourism, gaming, IT services, and many others.

What is the difference between cloud solutions and on-premise solutions? How to connect cloud-based DDos-mitigation solutions?

Premise-based appliances for DDoS protection are installed directly at customer data centres, alongside other networking equipment like routers, firewalls and servers itself. This approach offers the advantage of complete control over the infrastructure, allowing for easy updates, modifications, additions, or removals to the DDoS protection system whenever needed. 

 However, many organizations have budgetary concerns when considering such a DDoS mitigation solution. The cost of a DDoS mitigation appliance can vary from tens of thousands to hundreds of thousands of dollars. Additionally, there are often additional expenses for support, maintenance, and dedicated staff required to manage the equipment, which can impact the overall total cost of ownership (TCO). 

 Finally, DDoS mitigation capacity of an on-premise solution is limited by a hardware installed and, which is no less important, by an available channel which means that a large-volume attack can fill a customer's pipe even before the on-premises device gets a chance to “scrub” the attack traffic. 

 On the other hand, Always-On cloud DDoS mitigation provides continuous and uninterrupted cloud-based protection against DDoS attacks. Cloud-based solutions generally offer a network capacity of the order of terabits per second and their bandwidth can be horizontally scaled without additional investments. These solutions eliminate the need for constant involvement of qualified specialists and manual configurations to defend against complex attacks. Traffic filtration operates 24/7 at a fixed monthly cost, enabling organizations to allocate a specific budget for DDoS attack protection and have better control over IT expenses. 

 Using a cloud-based DDoS mitigation solution offers several advantages, including reduced costs and faster deployment time. It eliminates the need for capital expenditures (CapEx) associated with purchasing appliances and relying on legacy architectures. 

 When it comes to connecting to cloud-based DDoS-mitigation solutions, the process is quite simple. Multiple connection options, including DNS and BGP, are available with the latter allowing protection of every piece of infrastructure against any attack. Additionally, customers are allowed to configure rules for filtering out unwanted traffic and blocking malicious requests.

Does CDN protect against DDoS attacks?

CDNs can effectively mitigate DDoS attacks going through the CDN. But initially, CDN wasn’t designed to provide security, and attacks directed at the organization’s public IP addresses or the origin servers can not be prevented by CDN-based protection.

 CDN speeds up your site and increases fault tolerance but doesn't provide guaranteed protection against powerful DDoS attacks and most DDoS vectors.

 Site optimization with CDN technologies should be used with a specialized DDoS protection service rather than instead of it.

What are Bots, and how to stop malicious bots activity?

Bots are automated software programs that can perform automated or repetitive tasks. Bots can be classified by their intent: some bots are good, some bots are bad, and some are “grey” (or neutral).
 Good bots offer significant value to businesses, enabling essential operations like web content indexing, uptight monitoring, and data analytics. However, malicious bots, used by cybercriminals, pose increasing threats through activities like data theft, competitive parsing, bruteforce hacking, and carrying out distributed denial of service attacks. These actions can result in substantial financial and reputational damages to businesses. To protect against malicious bots, organizations should employ a multi-layered approach that includes bot detection and mitigation techniques such as fingerprinting, and to a lesser extent, behavioral analysis. However, other methods such as filtering by ACLs, user agents, and rate-limiting have shown their failure.
