You have an external IT provider maintaining your computers, user accounts, network, backups and day-to-day support. When something stops working, you know who to call, employees have the access they need and systems generally work as expected. It is therefore understandable to assume that security is covered as well. However, IT maintenance and an independent security assessment are not the same thing.

For hotels, accounting firms, clinics, law firms and other businesses that outsource IT maintenance, having someone responsible for keeping systems operational does not necessarily mean that someone is separately assessing their exposure, user access, network segmentation or the consequences of a compromised account or device.

A system can work perfectly well and still have a security weakness

Day-to-day IT maintenance has a very practical goal: computers need to work, users need access to applications, the network needs to be available, backups need to run and technical problems need to be resolved as quickly as possible. A security assessment asks different questions. Which systems are accessible from the internet? Are there remote access paths that are no longer needed? Do users have more privileges than they actually require? Are different parts of the network sufficiently separated? What could an attacker do after compromising a single user account?

Such weaknesses do not necessarily cause failures or become visible during normal operations. A system can function without problems for years while still having an old access path, an unnecessarily exposed service, excessive permissions or a configuration that could allow an attacker to reach systems that would otherwise be inaccessible.

Your external IT provider may be doing an excellent job

A good IT provider knows the environment, maintains its systems and usually already implements a range of important security measures. They install updates, manage users, maintain backups, configure network equipment, protect endpoints and resolve problems when they occur. That does not necessarily mean that the same environment has undergone a separate security assessment.

The company that deployed the systems and maintains them every day primarily sees the environment through the requirements of business operations and stability. A security assessment looks at the same environment from a different perspective: what could be exploited, how far a compromise of one part of the environment could spread and which controls actually limit the impact of an incident.

This is not criticism of the external IT provider, nor is it a reason to replace them. An independent assessment simply serves a different purpose.

One compromised account can be enough

Smaller organizations often do not have hundreds of systems. They may have a few computers, business email, cloud applications, remote access and several services on which their daily operations directly depend. That is precisely why a single account or device can be particularly important.

In an accounting firm, a business mailbox may contain communications and documentation relating to many clients. In a hotel, a reception computer may have access to systems required for daily operations. In a clinic, a relatively small number of computers and user accounts may provide access to systems and sensitive data. In a law firm, business email, documents and cloud services may contain information relating to a large number of cases and clients.

The question is therefore not only whether someone can compromise a single user account. What matters is what that account allows them to do next. Can they access other systems or shared folders? Are credentials stored on the device? Can administrative interfaces be reached from ordinary user workstations? Can a compromised device communicate with parts of the network it does not need to access for everyday work?

These are the kinds of factors that determine whether a security incident remains limited to a single account or device or spreads further through the environment.

“But our IT provider also takes care of security”

They very likely do. Updates, backups, user management, endpoint protection and network configuration are all important parts of security. The difference is that a security assessment does not only check whether a particular measure exists. It also looks at how that measure is configured and what happens when one of the controls fails.

A backup may exist, but can the systems and data required for business operations actually be restored from it? Remote access may be protected, but who still has access and is that access still necessary? A firewall may be configured correctly, but can a compromised computer inside the network reach systems it should not be able to access?

An independent assessment therefore does not replace your external IT provider. In practice, it can provide them with specific findings that they can then verify and address.

A security assessment does not have to be a large project

For a company with a few or a few dozen employees, cybersecurity does not have to begin with new infrastructure, additional tools or a major project. It makes sense to first establish what the current environment actually looks like, what is exposed, who has access to what, how different systems are separated and whether there are weaknesses that represent a real risk to the business.

Such an assessment may show that most things are already configured well and that only a few specific issues need to be addressed. It may also uncover access left behind after an old project, a user account with more privileges than necessary, a device that is no longer used or a service that remains externally accessible even though there is no longer a reason for it to be.

What matters is knowing the actual state of the environment rather than assuming security is covered simply because IT is working.

External IT and security assessments are not competing roles

An external IT provider maintains systems and enables the business to operate every day. An independent security assessment examines whether there are weaknesses that may not be visible through normal day-to-day operations and what the consequences would be if someone exploited them.

These two roles can complement each other very well. The external IT provider knows the environment and can implement necessary changes, while a security assessment provides an independent view of exposure, access, configurations and the potential for a compromise to spread.

AresISEC security assessments start with the organization’s actual IT environment. The goal is not to replace an existing IT provider or look for problems where none exist, but to determine whether there are weaknesses that could have a real impact on the business and which of them make sense to address.

Having an external IT provider does not automatically mean that cybersecurity is covered.
