Cybersecurity for Businesses: Data Protection and NIS2 Compliance

This article is intended for companies – particularly SMEs and businesses operating in regulated sectors – that want to understand concretely how to structure corporate cybersecurity and prepare for NIS2 compliance without hindering business operations. We will start with the real problem of increasing attacks and sanctions, examine what is changing with NIS2, build a simple business case on the costs and benefits of data protection, and distinguish priorities for small, medium, and more structured companies. We will delve into five “non-negotiable” security controls (backup, MFA, email security, monitoring, training) and conclude with the role of IT partners, like Lanpartners, in transforming compliance into a competitive advantage.

Why does it make sense to talk about cybersecurity and NIS2 today

In recent years, theransomware attacks, data theft, and targeted phishing campaigns they have increasingly affected SMEs as well, causing operational disruptions, ransom demands, and reputational damage that is difficult to recover from. The growing digitalization of processes, also described in the path of Digital transformation in SMEs, has made infrastructure, applications, and data central to business continuity.

The type of attacks that affect businesses has become more targeted: attackers gather information on the victim, study their digital dependencies, and exploit specific vulnerabilities to maximize impact. In many cases, the goal is not just to block systems, but to steal sensitive data and then use it as leverage, threatening to publish confidential information about customers, suppliers, and employees.

For companies working with complex supply chains, or that store large amounts of personal and business data, this scenario means simultaneously managing business continuity, market reputation, and relationships with regulatory authorities. In this context, a digital security strategy for SMEs is no longer optional, but a basic requirement to be able to participate in tenders, collaborate with large groups, and respond to increasingly detailed security questionnaires.

In parallel, the European NIS2 Directive extends and strengthens the regulatory framework for the security of networks and information systems, bringing many more companies under a perimeter of formal obligations. For companies, this means moving from a “reactive” approach to security to a structured cybersecurity model for companies oriented towards cyber risk management.

The problem: high risk, fragile infrastructure, and more stringent requirements

In many organizations, IT infrastructure has grown incrementally: servers added over time, outdated VPNs, firewalls not always updated, backups present but untested, and weak policies on passwords and access. In this scenario, the probability of operational downtime, data loss or encryption, and significant economic impacts in the event of an incident increases, as also shown in the focus. Digital threats: protect your business.

The new regulation, on the other hand, requires adequate technical and organizational measures, incident management procedures, and continuous monitoring of critical aspects. For many companies, this means bridging a gap between current practices and the required level of security maturity, especially in light of the data protection obligations introduced by European initiatives such as the Data Act 2025.

What does NIS2 ask of companies (in practice)

From an operational perspective, NIS2 can be translated into a few key requirements:

• Risk governance, with defined roles and responsibilities.
• Documented information and infrastructure security policies.
• Minimum technical measures: vulnerability management, regular patching, strong authentication, data encryption, network segmentation.
• Updated and tested business continuity and disaster recovery plans.
• Security event monitoring and incident response procedures.
• Structured training and awareness programs for staff and collaborators.

For the official requirements framework, the NIS2 Directive is described on the European Commission's website in the section dedicated to securing networks and information systems. For more complex projects, these elements are often integrated with other regulatory and legislative references, including the developments introduced by the’AI Act 2026 for artificial intelligence-based solutions.

A simple business case for cybersecurity

Build a Cybersecurity business case For companies, it means estimating the ratio between the cost of protection measures and the potential economic impact of a serious incident. Some key variables include: probability of an incident, downtime days, average daily revenue, extraordinary restoration costs, potential sanctions, and reputational damage.

On the cost front, infrastructure and services such as backup and business continuity, perimeter and endpoint protection, vulnerability management, training, and monitoring are typically considered. A concrete example is the adoption of solutions for Cloud backup and business continuity, which allow for rapid restoration of data and services in the event of an incident, reducing the overall business impact.

A practical way to build the business case is to start with one or two realistic scenarios, for example: “What happens if I cannot issue invoices for 3 days?” or “What happens if I lose the project history of the last 5 years?”. Starting from these questions, it is possible to estimate a potential damage range, including not only the immediate shutdown but also the slowdown of activities in the following weeks, the time spent by management in emergency meetings, and the unplanned hours of external consultants.

Once this fork in the road is defined, it becomes easier to compare the investment required for a three-year security plan (backup, monitoring, vulnerability assessment, training, infrastructure upgrades) with the cost of a single serious incident. In many cases, especially for SMEs, the cost of just one serious breach is sufficient to more than repay the investment needed to raise the level of cybersecurity for companies, as is also shown by analyses of corporate cybersecurity scenarios.

Small, medium, and large companies: same logic, different priorities

The underlying logic applies to all companies, but the priorities change based on size and organizational complexity.

Small businesses

Small companies often lack a structured internal IT department and rely on an external partner for the ongoing management of infrastructure, helpdesk, and critical services. In these contexts, the main objective is to build an essential yet solid security foundation: email protection, strong authentication, reliable backups, and a correct design of the business networking.

Medium-sized businesses

In medium-sized companies, the application ecosystem is more complex (ERP, CRM, production software, hybrid environments) and requires greater integration between technical measures and processes. The formalization of policies and procedures, the introduction of centralized logging and monitoring systems, as well as periodic security posture assessments become central. Within this framework, activities such as Vulnerability assessment and penetration testing They help to identify the most exposed areas and to define concrete priorities for intervention.

Large or high-criticality companies

Large companies or those operating in critical sectors (energy, transport, healthcare, finance, essential services) are more often included in the direct scope of NIS2 and other specific regulations. In these contexts, security is managed as an ongoing program, with reference frameworks, periodic audits, and particular attention to the supply chain. The design and evolution of the infrastructure – often based on data centers, virtualized environments, and cloud – require 360-degree cybersecurity approaches for companies, such as those also adopted in projects Cybersecurity for law firms in 2026.

In all these dimensional bands, the role of internal IT (when present) also changes: in smaller realities, IT is often focused on solving daily problems and on operations, while in medium and large ones, it is called upon to participate in defining policies, processes, and strategic technological choices. In practice, IT is no longer just “who fixes computers,” but a function that works together with management, compliance, and other business functions to define priorities, service levels, budget, and the security evolution roadmap.

In this context, it's often useful to have a partner who understands both the technical and regulatory aspects, capable of translating NIS2 requirements into concrete actions: which systems to update first, which logs to collect, which controls to budget for this year, and which to plan for subsequent years.

Five “non-negotiable” controls for corporate security

Regardless of the industry, every company can start with five basic checks that form the minimum core of an effective corporate cybersecurity strategy.

1. Backup and Disaster Recovery

Well-designed backup systems, with encryption, redundancy, data immutability, and periodic recovery tests, help limit the impact of ransomware or human error. The goal is to ensure not only data copies but also rapid recovery of critical services in emergency scenarios, thanks in part to solutions like Cloud Run BC Service Desk Think about business continuity with cloud services.

2. Strong authentication and identity management

Multi-factor authentication (MFA) for administrative accounts and privileged users drastically reduces the risk of compromises related to stolen or reused credentials. Coupled with robust password policies, centralized identity management, and timely revocation of access upon departures, it becomes an essential requirement for compliance purposes, especially in preventing scenarios of digital identity theft increasingly frequent in the corporate environment.

3. Email, Data, and Hybrid Work Protection

Email remains one of the main attack vectors, including phishing, malicious attachments, and links to compromised sites. Advanced filtering systems, attachment analysis, certified email protection where used, and correct DNS and email authentication settings are key elements to reduce the risk of incidents related to digital communication, in environments often based on tools like Microsoft 365 and hybrid work scenarios.

A typical example is the phishing campaign that simulates communication from the company's most used bank or cloud service provider. A single click on a malicious link can lead to credentials being entered on a fake page, paving the way for unauthorized money movements, changes to supplier bank details, or unauthorized access to management's email.

With appropriate email filtering solutions, link checks, strong authentication on critical accounts, and regular training, the risk associated with this type of attack is significantly reduced, transforming the user from a weak link into an active part of the defense.

4. Monitoring, logging, and vulnerability management

Collecting and analyzing security logs allows for the detection of anomalous behavior and intrusion attempts, while vulnerability management serves to reduce the “attack surface” through patches and correct configurations. In this context, a structured corporate network, with segmentation, next-generation firewalls, and well-defined access rules, helps to limit the propagation of any compromises and integrates with cloud and on-premises solutions described in the section Modern IT technologies for businesses and professionals.

5. Continuous training and incident response plans

People remain a crucial element of security posture: seemingly minor errors can pave the way for complex attacks. Recurring training and awareness programs, supplemented by practical examples and simulations, documented and tested incident response plans are required by both good practice and regulatory standards at least once a year.

An often underestimated element is the periodic testing of incident response plans: simulating an attack scenario, even just once a year, allows for verification of reaction times, clarity of roles, and the quality of available information. In many cases, these exercises reveal simple areas for improvement (e.g., outdated contact lists, documents that are not easily accessible, unmapped critical dependencies) that can be corrected before finding oneself in a real emergency situation.
