Simplify with Network Security as a Service (NSaaS)

    Digital transformation has changed from an IT buzzword to a commonly used term. Over the past two years, interest in digital transformation has grown due to an increased reliance on remote working models due to the COVID-19 pandemic. Moving an organization’s applications and data to the cloud offers many benefits, such as reduced operating costs and increased competitive advantage. However, it also expands an organization’s cyber attack surface and makes them more vulnerable to many cyber threats.

    Cybersecurity has become a necessity in almost every industry. But even for technology companies, the nuances of cybersecurity can fall outside the organization’s area of ​​expertise.

    To combat growing cyber threats, organizations of all sizes and industries work every day to strengthen their cyber defenses. Investing in cybersecurity awareness training and installing the latest technology security products (both software and hardware) is how most organizations combat the growing number of cybercriminals. online threats. However, in a landscape of complex threats that change almost daily, combating every risk is complex and can be resource-intensive if you plan to manage cybersecurity on your own.

    This article discusses a new cloud-based network security deployment service that is used to inspect and protect against ingress, egress, and malicious east-west traffic in an individual’s network. organization: network security as a service (NSaaS). It also introduced Trend Micro Cloud One™ — Network Security as a pioneer in this area.

    What is Cybersecurity as a Service (NSaaS)?

    While cybersecurity concerns can be addressed by maintaining an in-house cybersecurity team, organizations can also opt for solutions such as network security as a service (NSaaS), reducing network security burden and free up internal resources.

    NSaaS is a modern cloud solution run by a managed security service provider. NSaaS works by controlling and managing all security solutions installed on the client’s network perimeters. Managed solutions include firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), security information and event management (SIEM), and anti-spam systems. It also monitors all digital interactions in a customer’s IT environment to detect cyber threats early and respond to them quickly.

    Today’s IT environment is more complex than before. Modern IT environments include on-premises and cloud environments. The variety of users accessing these environments, such as the organization’s employees, third-party vendors, contractors, subcontractors, and other vendors, further adds to the complexity. . The number of Internet of Things (IoT) devices is also increasing, which means there are more entry points for cyber attackers to exploit.

    These emerging issues make dealing with the security of a computer network without seeking outside help from a professionally managed service provider a difficult and error-prone task. latent. In cybersecurity, it is very important to avoid errors that lead to a security incident because one mistake can destroy an entire business.

    An NSaaS provider does more than simply deal with security configuration issues of network perimeters. For instance, NSaaS also takes care of identity and access management, and recommends security rules that all users must follow when accessing your IT environment.

    NSaaS: The Solution to Many Cybersecurity Challenges

    IT leaders around the world appreciate the importance of cybersecurity capabilities in mitigating cyber threats and reacting to them quickly when they occur. For example, your internal cybersecurity teams are responsible for performing the following tasks to ensure the security of your organization’s network:

    • Track vulnerabilities across the entire IT environment, including endpoints, servers, IoT, and cloud applications, and work to address them promptly.
    • Monitor security protection solutions, such as IDS and IPS, firewalls, anti-virus, anti-malware, and SIEM.
    • Identify suspicious attacks and activities and respond to them before they escalate.

    An in-house security operations team can be obtained for large-scale organizations. However, most companies worldwide are small and medium sized. They can’t afford to have an entire cybersecurity team. For example, having an in-house security operations team can have the following disadvantages:

    • Budget constraints — Maintaining your in-house security teams requires significant spending to assemble a team of experts with a variety of cybersecurity skills.
    • Lack of experts — Finding a professional cybersecurity expert is not easy. If your team has a lot of vacancies that you can’t fill, a threat can exploit this to attack your organization.
    • Challenge to Retention — Let’s say you’ve successfully assembled the perfect cybersecurity team. Now, how many team members would you like to stay with you? For example, experienced members may leave another company after a while to get a raise. In contrast, less professional employees can work with your company for a year or two to gain experience and then move to another company.
    • Difficult to manage — Your cybersecurity team is responsible for all aspects of cybersecurity operations. Managing all team members is difficult as you will always need a reputable manager to oversee team work all day, every day.

    Outsourcing your cybersecurity needs to an external security provider offers many benefits to your organization, such as:

    • Significantly reduce costs. Maintaining internal teams will cost you a considerable amount of money. For example, hiring a professional cybersecurity engineer will cost you more than $100,000 annually, while hiring an outside vendor to outsource your entire cybersecurity operation will cost you significantly less. tell. Also, most NSaaS providers will offer their services on a subscription basis. Customers can choose the tier that best suits their current workload and increase it later if needed.
    • The use of highly specialized cybersecurity professionals, even if the number of skilled IT professionals is small compared to market demand. For example, according to Cybersecurity Ventures, there are 3.5 million unfilled cybersecurity jobs worldwide. An NSaaS provider you manage can hire the best talent in a field that small and medium-sized companies (SMEs) can’t afford.
    • Managed security vendors leverage advanced security solutions, such as network detection and response (NDR) and other proprietary solutions, to protect data and computer networks. They use the latest computing technologies (machine learning and artificial intelligence) to detect threats such as unknown malware and zero-day exploits.
    • Strengthen your overall network defense. Outsourcing your cybersecurity protection to an experienced external provider allows your organization to use the latest technology protections and get support from security experts. professional and knowledgeable cybersecurity who works around the clock to protect sensitive resources from ever-changing threats.
    • Ultimately, outsourcing your cybersecurity needs allows your in-house IT experts to focus on your organization’s goals while delegating the repetitive tasks of network monitoring and troubleshooting. to an outside professional security provider.
