A growing number of organizations are looking closely at cybersecurity-as-a-service — an outsourced model for managing risk on a pay-as-you-go basis. This approach offers a cost-efficient, adaptable, and expandable means to handle cybersecurity threats, enabling businesses to concentrate on their primary operations.

In this article, you will learn:

  • What is cybersecurity-as-a-service, and what is the difference from traditional cybersecurity? And what benefits can it provide?
  • What types of cybersecurity-as-a-service companies are out there? What are their top services?

What is cybersecurity-as-a-service

Cybersecurity-as-a-service (CSaaS) is a model where organizations subscribe to or outsource their cybersecurity needs to a third-party service provider. In this model, the service provider delivers a range of cybersecurity services, tools, and expertise to help protect an organization's digital assets and information systems from cyber threats and vulnerabilities. 

CSaaS encompasses various critical security elements to ensure comprehensive protection for organizations. These elements include:

  • Application security. Protection of sensitive credentials and applications from email-based attacks is part of this process.

  • Endpoint security. It extends beyond traditional firewalls to include securing connected devices remote workers use. This ensures that devices outside the corporate network are protected against potential threats.

  • Data security. CSaaS focuses on securing data when it is in motion (being transferred) and at rest (stored). As a result, data remains protected throughout its lifecycle.

  • Network security. CSaaS includes measures to filter out harmful traffic and block potential intruders from accessing the network. By doing so, the integrity and confidentiality of the network infrastructure can be maintained.

  • Cloud security. CSaaS covers security measures for multi-cloud environments, ensuring that data and applications hosted in the cloud are protected against unauthorized access and other potential threats.

  • Managed detection and response (MDR). CSaaS providers offer MDR services, which involve actively monitoring systems and networks for any signs of threat activity. If a threat is detected, the provider will respond quickly to neutralize it.

How does cybersecurity-as-a-service differ from traditional cybersecurity

Managing cybersecurity in-house is challenging, especially with digital transformation and IoT. As businesses go digital, the attack surface grows. Meeting the security expectations of both employees and customers is crucial.

Traditionally, the construction of an internal security team involves hiring experienced professionals dedicated to creating and enforcing a company-wide security strategy tailored to the organization's needs. However, this approach can be resource-intensive and time-consuming, especially for larger enterprises with extensive staff and systems spread across multiple locations. As organizations grow, in-house security efforts can strain available resources.

CSaaS provides an outsourcing alternative. Some companies prefer a comprehensive approach, where they partner with a single vendor to handle all their security needs. Others delegate specific enterprise security functions either partially or entirely to external providers.

The top benefits of CSaaS include:

  • Reduced risks
  • Greater efficiency
  • Lower costs.

Some organizations take a more flexible approach to CSaaS, opting to outsource certain aspects to a vendor while retaining others in-house.

How does cybersecurity-as-a-service work

CSaaS integrates top-tier security services, software, and human expertise into a comprehensive solution.

At the core of every CSaaS provider is their security operations center (SOC), a cutting-edge facility dedicated to monitoring and addressing security threats for your organization. These SOCs are typically staffed by experienced security professionals committed to monitoring, identifying, tracking, and resolving security incidents. They leverage high-level security software and advanced tools to detect and prioritize system threats.

Within the CSaaS framework, the SOC utilizes technology and human knowledge to oversee your business systems for security risks. This approach may encompass cutting-edge technologies like artificial intelligence (AI), managed detection and response (MDR), managed incident response, endpoint security, application security, data security, and cloud security. SOC teams may also proactively hunt for potential threats using diverse methods, including social media monitoring, dark web intelligence, and open-source intelligence.

Organizations eliminate the need to establish their security tools and processes by opting for cloud-based or subscription-based CSaaS. Some managed security providers can initiate environment monitoring within days or weeks, ensuring proactive protection and peace of mind more rapidly than traditional in-house security models.

What benefits can CSaaS provide

Some key benefits of CSaaS include:

  • Cybersecurity resources are managed centrally
    CSaaS simplifies cybersecurity resource management by enabling organizations to oversee and prioritize their cybersecurity efforts from a single, convenient location.

  • Scalability
    Today's businesses adapt to a dynamic global economy, causing cybersecurity needs to shift over time. CSaaS offers flexibility, enabling organizations to optimize resource allocation and avoid overspending on unnecessary features.

  • Detection and response capabilities are automated
    CSaaS platforms often include automated threat detection and response capabilities, enabling swift actions against cyber threats, reducing the impact of attacks, and safeguarding critical data.

  • Integrated security solutions
    Numerous CSaaS platforms offer integrated security solutions, simplifying the deployment of comprehensive cybersecurity strategies to protect all systems. It is a valuable tool for businesses seeking enhanced cyberattack protection, with various options available to meet specific organizational requirements.

What types of cybersecurity-as-a-service companies exist

Four types of cybersecurity companies

Running an in-house SOC is often too complex and costly for many companies. Managed cybersecurity services from specialized companies offer similar protection at a much lower cost. However, it is essential to recognize that cybersecurity services can differ among providers. By understanding the common categories of cybersecurity vendors and managed security service companies, you can better assess your specific cybersecurity requirements.


Suitability: For companies of various sizes, it offers comprehensive tech infrastructure management, cybersecurity services, and network security components.

Managed service providers (MSPs) are external companies overseeing an organization's tech infrastructure and services. They typically include various network security components within their services, which play a crucial role in managing the structural aspects of your cybersecurity solution. This includes firewall management, email security, sandboxing, data loss prevention, and access control. MSPs also handle tasks such as updates and patches to address potential vulnerabilities. It is worth noting that traditional MSP services primarily focus on on-premises network cybersecurity, and they generally do not have an off-site SOC to assist.


Suitability: Suitable for small to large companies, especially those lacking dedicated in-house cybersecurity teams. Provides a comprehensive security approach.

Managed security service providers (MSSPs) are specialized tech service providers primarily focusing on cybersecurity. They deliver comprehensive network security monitoring and management services that cover an organization's entire tech environment. Many MSSPs offer 24/7 network monitoring, along with additional services like vulnerability management and security configuration. Common services provided by MSSPs include managed firewall services, intrusion detection, virtual private network management, vulnerability scanning, antivirus services, and security information and event management (SIEM) monitoring.


Suitability: Suitable for companies of all sizes, it provides proactive threat detection, incident response, and cybersecurity expertise to enhance security.

Managed detection and response (MDR) is a comprehensive 24/7 cybersecurity solution that actively seeks out, identifies, and promptly alerts organizations about existing or incoming threats. While MDR and managed security service providers (MSSP) offer cybersecurity services with various tools and features, MDR is inherently more proactive. It leverages cutting-edge technologies to combat modern cyber threats, utilizing integrated tools for proactive threat detection, hunting, and response. MDR is staffed by real experts, with live threat hunters continuously monitoring client networks in real time to identify indicators of attack and compromise. One of the key services MDR providers offer is extended detection and response (XDR).

Co-managed tech service providers

Suitability: Suits companies of varying sizes and offers flexibility and specialized expertise to complement internal tech teams or address specific tech needs.

Co-managed tech service providers collaborate with an organization's existing tech services. They rely on the internal tech team's expertise to deliver supplementary services that help the organization bridge potential security gaps. Organizations with in-house solid tech teams can benefit from tailored co-managed services that maximize the combined knowledge of both teams. These services can encompass a range of offerings, from co-managed security information and event management (SIEM) to security operations center as a service (SOCaaS).

How much do cybersecurity-as-a-service provider's services cost

On average, consider allocating 5.6% to 20% of your budget to cybersecurity. Depending on your company size or specific services, costs may differ.

Outsourced cybersecurity services generally start at a minimum cost of $2,000 to $3,500 monthly. On a per-user basis, this equates to a range of $195 to $350 per user, covering support and maintenance. If you already have support, the standalone cybersecurity cost is typically $35 to $65 per user.

In the third quarter of 2022, there was a 28% increase in worldwide cyberattacks, and the average expense of data breaches rose by 12.7% compared to 2020, reaching $4.35 million. These services play a crucial role in protecting sensitive information, preventing substantial penalties and ransom costs, as well as mitigating long-term reputational harm. Additionally, they assist in establishing proactive security initiatives, ensuring adherence to regulations, and effectively addressing cybersecurity incidents.
