How to build digital resilience in your company

A company’s operations can stop not only after a cyberattack. It can be caused by an incorrectly implemented system update, an unavailable cloud service, a broken internet connection, a supplier’s mistake, or the mistaken actions of a single employee. Digital resilience determines whether, in such moments, an organization can continue providing services, taking orders, serving customers, and protecting critical data.

In a small or medium-sized business, this issue often only reaches the agenda after the first serious incident. Until then, the IT environment usually has been built gradually: new users, separate cloud tools, added branches, remote work, and various external suppliers. Each solution can be useful on its own, but without shared management they create dependencies that become visible very quickly when something fails.

What digital resilience means for a company

Digital resilience is a company’s ability to anticipate digital risks, withstand disruptions, restore operations quickly, and use the experience gained so that losses are smaller next time. It is broader than cybersecurity. Cybersecurity seeks to prevent incidents, while resilience accepts that some incidents cannot be completely prevented.

In practical terms, this means management has clear answers to several questions. Which systems are essential for revenue and customer service? How much downtime can the company afford? How old can the data be that is restored after a failure? Who makes the decision if the main system is unavailable? And are these answers tested in practice, not just written in policy?

Resilience is not a single software license or backup copy. It is a management discipline that combines infrastructure, security controls, backup solutions, people’s actions, and management decisions. If any of these parts does not function, the others cannot always compensate for the shortcoming.

The true cost of downtime

The cost of downtime is not just an unissued invoice for a few hours. For a manufacturing or logistics company, it can mean a halted supply chain. For a professional services provider - unavailable client documentation and missed deadlines. For an e-commerce company - orders going to a competitor right at the moment when demand is highest.

Secondary consequences must also be considered: employee time for manual work, urgent external specialist services, contractual penalties, loss of customer trust, and management attention diverted from development to crisis management. In some cases, the biggest losses occur not during the incident, but in the weeks after it, when data must be restored, the situation explained to customers, and processes put in order.

Therefore, the right question is not whether the company can afford to invest in resilience. The question is how expensive an uncontrolled shutdown would be and how much of that risk it is reasonable to reduce.

Start with business priorities, not a list of technologies

A resilience plan begins with identifying the company’s critical processes. The accounting system may be important, but it does not always need to be restored in the first hour. Meanwhile, customer order processing, warehouse management, access to production equipment, or customer support channels may already be critical after just a few minutes.

At this stage, a business impact analysis is useful. Its purpose is to connect IT systems with actual company processes and determine priorities. Management, together with responsible employees, evaluates what happens if a specific service is unavailable for one hour, one day, or longer.

It is important to agree on two goals. The recovery time objective determines how quickly the system must be back in operation. The recovery point objective, in turn, determines how much data loss is acceptable. For example, if order data may be lost by no more than 15 minutes, one nightly backup will not be enough. If the archive document system can be unavailable for a day, the solution does not necessarily have to be as expensive as an online sales platform.

There is no universal configuration here. Unthoughtful overprotection increases costs and administration, while insufficient protection creates a risk from which the company may not recover. Decisions should be based on business impact, not on the assumption that everything must be equally available quickly.

A backup is not yet a recovery plan

Many companies think that having backups automatically solves business continuity. It does not. A backup is only one of the elements needed for recovery. It must be known whether the data is complete, whether it can be restored within the required time, whether the copies are protected from a ransomware attack, and whether the recovery procedure is documented.

Especially dangerous is a situation in which backups are stored in the same environment that can be reached with a compromised administrator account. In a ransomware incident, attackers often try to delete or encrypt the backups themselves so that the company is left with no other choice but to pay the ransom.

A well-designed approach provides for several layers of copies, separate access control, and at least one copy that cannot be easily altered or deleted. But the critical step is a regular restore test. If the company has never tried to restore an important system, it does not know whether the backup really meets the promised recovery time.

People and suppliers are part of the infrastructure

Technical guidelines alone will not protect a company if an employee approves a fake payment request or enters access data on a fraudulent site. Multi-factor authentication, access rights management, and regular training reduce this risk; however, human error will not disappear completely. Therefore, processes must be designed so that one mistake does not cause disproportionate consequences.

For example, administrator rights should not be granted for everyday work, but important financial or data deletion decisions should require additional approval. When an employee leaves the company or changes roles, access must be removed in a timely manner. These steps sound simple, but they are often skipped if there is no clear responsibility and centralized management.

External suppliers must be assessed in the same way. A company may depend on an internet provider, a cloud platform, an accounting system, a payment service, or an IT partner. It must know the supplier’s incident escalation process, how access to data is ensured, and what the company will do if the service is unavailable for a prolonged period. A full backup supplier is not always necessary, but critical dependencies must be identified.

The incident plan must be usable under pressure

During an incident, no one has time to search for outdated contacts, access passwords, or debate who may shut down a system. An effective incident response plan is short, specific, and available even if the company’s main tools are not working.

It should define roles, contacts, the first technical actions, communication procedures with employees and customers, as well as criteria for involving management, an insurer, a lawyer, or a security specialist. It should also specify separately how to preserve evidence, because a rushed system restart can make it harder to determine the cause of the incident.

The plan must be tested with practical scenarios. For example, the management team can rehearse a situation in which the file system is encrypted, the email environment is unavailable, or a suspicious data leak is detected. Such tests reveal not only technical shortcomings, but also delays in decision-making and unclear communication.

Resilience must be maintained as a management process

The digital environment changes along with the company. A new branch, an acquired company, a replacement of the sales system, the introduction of remote work, or a new cloud service also changes the risk set. Therefore, a one-time audit is a valuable starting point, not the destination.

Regular review of IT and business continuity helps management see whether critical systems still match business priorities, whether backups are being tested, and whether supplier responsibilities are clear. Such a review is especially important before a company sale, merger, financing round, or significant growth, when IT risks become a commercial issue.

In KSK IT practice, resilience work is most effective when it is managed as a company priority rather than an isolated technical project. Start with one specific question: what would happen if your most important system were unavailable for four hours tomorrow? An honest answer often shows where to invest first.
