How to answer the security section of a tender

Why buyers put security in a tender at all

When a government agency or a larger company brings you on, your systems end up connected to theirs. If you get breached, it is their data and their name exposed too. The security section is how the buyer works out whether hiring you brings a level of risk they are not willing to carry.

Once you see it that way, the right answer gets obvious. It is not a claim that you are secure. It is a plain account of how you look after their information, with something to back it up. Your job here is to settle a nervous buyer, not to impress anyone.

The questions that come up again and again

The wording shifts from one tender to the next, but the themes barely move. Most of them map straight onto the Essential Eight and the Privacy Act.

How do you control access to systems and data?

Whether you use multi-factor authentication, whether access is kept to the people who actually need it, and whether someone who leaves loses their access quickly. Answer it plainly. MFA is on for email and the main systems, admin rights sit with a few named people and get reviewed, and accounts are shut off the day a person walks out.

How do you keep systems up to date?

Whether you keep operating systems and applications patched, and whether you are running anything the vendor no longer supports. A couple of sentences on how you patch and how often will do.

How do you back up and recover?

Whether you could actually get their data back after ransomware or a dead server. Say that you back up, that at least one copy sits somewhere an attacker cannot reach, and that you have tested a restore rather than assumed one.

What happens if you have a data breach?

Whether you have a plan for a bad day, and whether you know what the Notifiable Data Breaches scheme asks of you, including telling affected people and the OAIC when the law requires it. A short summary with a policy to point to tends to score well.

What policies and training do you have?

Whether security is something you manage on purpose or make up as you go. List the policies you actually have in writing, and confirm that staff get some basic security awareness training.

Do you use subcontractors or overseas providers?

Whether their data will end up with other companies, or stored overseas. Be straight about it. Name your main providers and say where the data lives.

How to write answers that score

• Answer the actual question. Do not drop in a generic security paragraph and hope. Line each answer up with the question in front of you and the marks it carries.
• Be specific, and be honest. "MFA is on for email and remote access" beats "we follow industry best practice" every time. If a control is only half done, say so, and say what you are doing about it. Assessors can smell spin.
• Use the frameworks they already know. Tying your answers back to the Essential Eight and the Privacy Act tells the buyer you speak their language.
• Attach something. A dated assessment, a policy, or a certificate turns a claim into something the buyer can check for themselves.
• Keep it readable. Short paragraphs, plain words. Whoever is scoring has a stack of these to get through.

The evidence to have ready

The businesses that turn these around fastest are the ones that put the folder together long before a tender showed up:

• A one-page summary of your security posture and readiness score.
• Written policies — access control, incident response, data breach, backups, acceptable use.
• Proof that MFA and tested backups are in place.
• A dated readiness assessment or certificate showing your position is current.
• A short list of your key IT and cloud providers and where data is stored.

Mistakes that quietly lose points

• Vague reassurance. "We take security very seriously", with nothing behind it, reads as having nothing to show.
• Overclaiming. Claiming a standard you do not meet is worse than owning the gap. It can void the contract down the track.
• Skipping the Privacy Act and NDB. If the work touches personal information, leaving these out is a gap buyers do notice.
• Leaving it to the last night. If the controls are not already there, no amount of good writing will conjure them before the deadline.
• Nothing attached. Answers with no supporting document are the most common reason a capable business scores badly here.

Questions we get asked

Do I need to be certified to answer a tender security section?

Usually no. Most SMB-facing tenders ask you to describe your controls and provide evidence, not to hold a formal certification like ISO 27001 or an IRAP assessment. Certification helps on larger or higher-classification contracts, but for most work, clear, honest, evidence-backed answers mapped to the Essential Eight are enough.

What evidence should I attach?

Have ready a short summary of your security posture, your written policies, proof that MFA and backups are in place, and a dated readiness assessment. Attaching a dated report or certificate shows a buyer your position is current rather than asserted.

How long does it take to prepare a response?

If your controls and policies already exist, writing the response is a day or two. If you are starting from nothing, the bottleneck is putting the actual controls and documents in place first — which is why it pays to prepare before a specific tender lands with a deadline.
