Key cybersecurity insights and how Insta helps organisations prepare

The cybersecurity threat level has remained high in recent years, while systems, regulation and the operating environment have become increasingly complex. From a penetration testing perspective, cybersecurity in Finland is at a good level in many respects, but recurring vulnerabilities are still being identified.

This is where Insta supports its customers with practical, hands-on cybersecurity expertise.

Reducing vendor dependency can introduce new risks

Solutions aimed at reducing vendor dependency can be justified from a business continuity perspective, but they may also introduce increased security risks. When a solution differs from widely adopted technologies, its security architecture, integrations and maintenance practices may not have been as extensively tested or established. MFA implementations and other critical authentication solutions, in particular, should be carefully and independently assessed before they are relied upon as part of an organisation’s security controls.

How Insta can help:

  • Penetration testing and technical security assessments

  • Comprehensive assessments of MFA and other security implementations

  • Reviews of access rights and backend systems

Even minor implementation flaws can undermine otherwise well-designed security controls, creating only an illusion of security. Penetration testing helps identify these vulnerabilities before someone else does.

The supply chain is increasingly the weakest link

As larger organisations strengthen their baseline security, attackers are increasingly targeting subcontractors and partners. A single organisation’s weak security practices can provide an entry point into the wider supply chain.

How Insta can help:

  • Assessing supply chain security

  • Defining cybersecurity requirements for subcontractors

  • Developing cybersecurity practices and capabilities

We have extensive experience operating as part of critical supply chains, giving us first-hand insight into what is required of organisations – and why.

Penetration testing can also help mitigate denial-of-service attacks

Denial-of-service (DoS) attacks are becoming increasingly common and sophisticated. More advanced forms, such as application-layer attacks, can disrupt or take down a service without requiring massive volumes of traffic or extensive technical expertise.

How Insta can help:

  • Penetration testing of applications and APIs

  • Identifying vulnerabilities that can be exploited to cause excessive resource consumption

  • Planning security controls and preparedness measures

Attacks can be prevented, or their impact significantly reduced, when vulnerabilities are identified early.

Collaboration and exercises turn preparedness into practice

There is no such thing as perfect protection. The best results are achieved when cybersecurity is developed collaboratively and response capabilities are tested in practice.

How Insta can help:

  • Preparing for cyber threats and supporting cybersecurity exercises

  • Building joint operating models for organisations and their subcontractors

  • Enabling the secure sharing of observations and lessons learned

Exercises almost invariably uncover areas for improvement that may not become apparent in day-to-day operations.

When something raises concern, it is time to act

Often, the first indication of a potential security issue is simply the thought: “Should we have this checked?”

This question may arise when a new system is about to be deployed, the replacement of a legacy system has been delayed, or a security assessment has not been carried out for a long time – or at all.

How Insta can help:

  • Proactive security assessments

  • Penetration testing before vulnerabilities lead to incidents

  • Expert support when decisions need to be made quickly

A small proactive investment is often only a fraction of the cost and disruption caused by a serious cybersecurity incident.

Insta’s areas of expertise

Insta has extensive, long-standing experience in areas including:

  • Penetration testing and technical cybersecurity

  • Securing critical infrastructure and industrial automation environments

  • Supply chain and partner ecosystem security

  • Cybersecurity assessments, development and preparedness

Our role is to help customers see their systems through an attacker’s eyes – and address weaknesses before they become problems.
