Key Takeaways
- Vague SLAs are a warning sign. If a vendor can’t tell you exact response times and uptime numbers, they can’t be held accountable when things go wrong.
- A vendor’s own security posture tells you everything. How they protect themselves is how they will protect you.
- Hidden costs show up after you’ve signed. Always ask what’s included, what’s not, and what triggers extra fees.
- No real-world experience is a dealbreaker. Case studies, incident history, and references matter more than a polished pitch deck.
- The right questions during vendor risk assessment can save you from a very expensive mistake down the road.
Top Red Flags to Watch Out When Evaluating a Security Vendor
Vague SLAs
A solid SLA should have specific numbers. If a vendor says things like “commercially reasonable efforts” or “best endeavors,” that means nothing when you’re in a crisis. Push for exact uptime percentages, response times, and what happens if they miss those targets. No concrete numbers means no real accountability.
Poor Cyber Hygiene
If a security vendor can’t keep their own house in order, they won’t keep yours safe either. Look for things like outdated software, no patch management process, and weak access controls. Ask if they do regular penetration testing and vulnerability scans. A vendor with poor hygiene on their own systems is a liability, not a partner.
Gaps in Security and Compliance
Ask for certifications. ISO 27001, HIPAA, and SOC2 compliance are not optional extras. They are proof that a vendor takes security seriously. If a vendor shrugs at compliance requirements or can’t produce documentation, that is a major problem, especially if you operate in a regulated industry.
Hidden Costs
Many vendors price low to win the deal, then charge extra for incident response, additional users, integrations, and reporting. Ask them directly: what is not included in this price? Get everything in writing before you sign. Surprise invoices after an incident are the last thing you need.
Unclear Processes
A trustworthy vendor should be able to walk you through exactly how they detect threats, escalate incidents, and communicate with your team. If the answer is vague or shifts depending on who you ask, that tells you the process doesn’t really exist. You need a vendor with a clear, repeatable workflow, not improvised responses.
Using Fragile Technology
Old or patched-together technology breaks under pressure. Ask what tools and platforms they use. Ask how often they update them. Ask if they are running any end-of-life software. Security technology needs to be current because attackers are always current.
Lack of Security Policies
A vendor without documented security policies is winging it. They should have written policies for data handling, access control, incident response, and employee training. If they can’t hand you a policy document when you ask, that is a red flag.
Open Firewalls
Firewalls should be tightly configured, not wide open. Ask if they conduct regular firewall audits. Ask who has access to make changes. An open or poorly managed firewall is one of the most common entry points for attackers.
No Real Experience
Marketing materials and demo videos do not count as experience. Ask for real case studies. Ask how many security incidents they have handled and how. A vendor that has never been tested under pressure is an unknown risk. Look for references you can actually call.
What are the Questions You Should Ask for Vendor Risk Assessment?
These questions cut through the sales pitch and get you the answers that matter.
- Do you have cyber insurance and what exactly does it cover? Coverage gaps matter as much as the policy itself.
- How many security incidents and breaches have you experienced in the last three years, and how did you respond? A vendor with zero incidents either has great security or isn’t being honest. Push for specifics.
- Have you tested the backup and restore processes? Test means they have actually run a drill, not that the process exists on paper.
- Is there a documented protocol for both on-site and off-site backup storage? Redundancy only works if it is structured and verified.
- Do you maintain proper documentation for all your workflows and processes? Poor documentation usually means poor consistency when your team needs help fast.
- Do you support Single Sign-On (SSO)? SSO is a baseline security feature. If they don’t support it, that tells you something about how seriously they take identity management.
- Do you hold an ISO 27001 certification? This certification shows a vendor has a formal, audited information security management system in place, not just promises.
Conclusion
Picking a security vendor is one of the most consequential decisions your team will make. A bad vendor does not just fail to protect you. They can become the reason you get breached in the first place. The red flags in this post are not rare edge cases. They show up all the time in vendor evaluations, and they are easy to miss when you are moving fast or impressed by a polished pitch.
Take the time to ask hard questions, demand documentation, and verify claims before you commit. A vendor that gets uncomfortable with your questions is telling you something important. The right partner will welcome the scrutiny.
