Cybersecurity for SMBs: protect your business on a real budget

SMBs and mid-sized companies are cybercriminals' favorite target, not their lowest priority. We design security solutions that fit your size, budget and resources.

Why are SMBs a preferred target for cyberattacks?

43% of cyberattacks target SMBs. Attackers know that small and mid-sized businesses have weaker defenses, limited budgets and, in many cases, no dedicated security specialist. A ransomware attack can paralyze an SMB for weeks and cause losses of tens of thousands of euros. The good news: you don't need a multinational's budget to reach an adequate level of security.

What an SMB needs to stay secure

  • Vulnerability assessment: know where you're exposed
  • Patch management: keep systems and software up to date
  • Email protection: SPF, DKIM, DMARC and anti-phishing training
  • Backup and recovery: the last line of defense against ransomware
  • Password management and two-factor authentication (MFA)
  • Managed security and SOC as a Service: continuous monitoring without building your own team
  • Cyber insurance: which controls your insurer requires and how to meet them before renewal
  • Basic NIS2 compliance if you're a digital service provider
  • Team training: the human factor is the most exploited vector
  • Basic incident response plan: knowing what to do when it happens

Our approach for SMBs

  1. Free initial diagnostic: A 30-minute call to understand your business, your most valuable assets and your current exposure level.
  2. Tailored proposal: We don't sell the same service to everyone. We design a security roadmap fitted to your real budget.
  3. Phased implementation: We prioritize the highest-impact improvements first. You don't have to do it all at once.
  4. Ongoing support: A single point of contact for all your security questions, without hiring an in-house CISO.
  5. Annual review: The threat landscape changes. We review your security posture and update the roadmap every year.

Frequently asked questions

How much does cybersecurity cost for an SMB?

It depends on your size and exposure. An initial diagnostic and a basic vulnerability assessment can run a few hundred euros. A managed security service for a typical SMB ranges from €300 to €800/month. We always start with what has the most impact for the lowest cost.

Am I required to comply with NIS2 as an SMB?

It depends on your sector and size. NIS2 directly obligates medium and large companies in essential and important sectors. However, many SMBs are indirectly obligated because they supply companies that must comply, and those companies require security guarantees from them.

Can you help us even if we don't have an IT manager?

Yes. We work directly with management or whoever handles IT informally at the company. No prior technical knowledge is required to work with us.

How long does it take to set up a cybersecurity plan for my SMB?

The highest-impact immediate measures (MFA, passwords, backups) are set up within days. An initial vulnerability assessment takes 1 to 5 business days depending on size. A full plan with assessment, guided remediation and basic policies is usually completed in 4-8 weeks. We always start with what has the most impact at the lowest cost.

My company has already suffered a cyberattack. What do I do now?

The first step is containment: isolate the affected systems, revoke compromised access and preserve evidence without altering it. Next, a basic forensic analysis determines how they got in, what was affected and whether they're still inside. If the incident involves personal data, you have 72 hours to notify the AEPD. Contact us: we do an initial triage to help you understand the situation before deciding next steps.

Do I need a CISO or an in-house security manager?

For most SMBs it's neither necessary nor viable. A senior CISO in Spain costs between €80,000 and €130,000/year. The alternative is a virtual CISO service or an external security partner: you set the objectives, we execute them and report back periodically. It's far more efficient for companies with fewer than 100 employees.

What is managed security and when does it make sense for an SMB?

It's a continuous monitoring and response service (SOC as a Service) without hiring an in-house team: we watch your systems, detect incidents and act on protocols agreed with you. It makes sense once you have critical assets to protect outside business hours but not the volume to justify an internal SOC.

Do I need cyber insurance on top of cybersecurity services?

They're complementary, not substitutes. Most insurers require minimum controls (MFA, backups, periodic vulnerability assessment) to issue or renew a cyber policy, and lower the premium if you can demonstrate them. We help you identify what your insurer requires and implement it before renewal.
