É mais do que tempo de chamar a atenção para uma das questões mais prementes que as empresas enfrentam atualmente - as ciberameaças. As pequenas e médias empresas (PME) são cada vez mais visadas pelos cibercriminosos, e as estatísticas são alarmantes. Eis algumas delas:

  • Almost 43% of cyberattacks target small and medium businesses—a reminder of just how important tools like endpoint protection and network monitoring are to detect threats early.
  • A surprising 96% of SMBs struggle to investigate suspicious alerts, which makes them even more vulnerable. Streamlined alerts and automated responses can make a real difference here.
  • Nearly 60% of small businesses close within 6 months of an attack. Having a solid recovery and backup plan is key to staying resilient against both financial and reputational damage.
  • Cyberattacks happen over 2,200 times a day—every 39 seconds. This pace highlights why continuous monitoring is essential to staying ahead of potential risks.
  • Com estes factos em mente, vamos compreender por que razão as PME são alvos privilegiados de ciberataques e, mais importante ainda, como se podem proteger.

    Por que as pequenas empresas são visadas?

    Pode parecer que grandes corporações com grandes quantidades de dados seriam os principais alvos dos cibercriminosos, mas as pequenas empresas costumam ser vistas como frutos fáceis. Por que? Aqui estão alguns motivos:

    1. Limited Resources: SMBs typically don’t have the same budget or dedicated cybersecurity teams as larger corporations, making it harder for them to invest in comprehensive security measures.

    2. Lack of Cyber Expertise: Many small businesses don’t have in-house experts who can identify, investigate, or respond to cyber threats effectively.

    3. Valuable Data: Despite their size, SMBs store sensitive information—like customer data, intellectual property, and financial records—which is valuable to hackers.

    4. Supply Chain Vulnerabilities: Small businesses are often part of larger supply chains. A breach in one SMB can compromise an entire network, making them an appealing entry point for cybercriminals.

    Formas como as pequenas empresas são visadas

    Os cibercriminosos utilizam uma variedade de tácticas para violar as pequenas empresas. Eis alguns dos métodos mais comuns:

  • Phishing Attacks: These involve emails that look legitimate but are designed to trick employees into clicking on malicious links or providing sensitive information.
  • Trojans: Malware that disguises itself as a legitimate program, giving hackers access to your systems and data once it’s downloaded.
  • Ransomware: Hackers use ransomware to lock down your data and demand payment in exchange for its release.
  • Credential Theft: Cybercriminals steal usernames and passwords to gain access to accounts, often through weak password policies or data leaks.
  • Wi-Fi Vulnerabilities: If employees connect to insecure public Wi-Fi, hackers can easily intercept their data and gain access to business networks.
  • Com ataques tão frequentes, a questão não é se a sua empresa vai ser alvo de ataques, mas sim quando.

    Seguro - É suficiente?

    Embora ter um seguro de cibersegurança possa proporcionar alguma paz de espírito, não é uma solução completa. O seguro de cibersegurança pode ajudar a cobrir os custos associados a uma violação, como honorários legais, coimas e despesas de recuperação, mas não impede que um ataque aconteça em primeiro lugar. De facto, se a sua empresa não dispuser de medidas de segurança adequadas, poderá ter de pagar prémios mais elevados ou mesmo ver a cobertura recusada.

    É por isso que é essencial associar o seguro a práticas proactivas de cibersegurança. A prevenção é sempre melhor do que tentar recuperar de um ataque devastador.

    Como é que os trabalhadores e as empresas podem trabalhar em conjunto para se manterem seguros?

    Os funcionários são frequentemente a primeira linha de defesa na prevenção de ciberataques. Devem ser informados sobre práticas seguras em linha, mas é necessário um esforço de equipa. Eis como os funcionários e as empresas podem trabalhar em conjunto:

  • Employee Education: Regular training on identifying phishing attempts, creating strong passwords, and using secure communication channels is crucial. Encourage employees to report suspicious activity without fear of repercussions.
  • Simulated Phishing Tests: Test your employees by sending fake phishing emails to see how they respond. This can help identify gaps in awareness and provide an opportunity for additional training.
  • Secure Devices: Make sure employees use company-approved devices for work, and implement strong security policies like multi-factor authentication and VPNs for remote access.
  • Cybersecurity Newsletters: Regular updates through emails or internal newsletters keep cybersecurity top of mind for employees, helping to reinforce good practices.
  • O que deve ser feito do ponto de vista da empresa?

    Do ponto de vista do proprietário de uma empresa ou do gestor de TI, é fundamental ter um plano de cibersegurança sólido. Eis alguns passos que pode dar para garantir que a sua empresa está protegida:

  • Develop an Incident Response Plan: In the event of an attack, having a clear incident response plan will help minimize damage and get your systems back online faster. Include procedures for communication if traditional channels are compromised.
  • Invest in Security Software: Use reputable security software to protect your systems from malware and unauthorized access. Update it regularly to stay ahead of emerging threats.
  • Regular Backups: Back up your data regularly and store it securely. This will help you recover your data without paying a ransom if you fall victim to ransomware.
  • Use Strong Password Policies: Implement company-wide password policies that encourage the use of complex passwords and frequent updates. Consider using a password manager to store passwords securely.
  • Monitor for Suspicious Activity: Regularly monitor your network for unusual behavior that could indicate a cyberattack. Having real-time alerts in place can help you respond quickly.
