Enterprise-grade security, right-sized to your organization. Ransomware, insider mistakes, and exposed vendors put the business itself at risk, not only the technology. Whatever you build or sell, we make sure you understand both the how and the why at every step.
The Meridian approach
For a lot of teams, security reads as pure cost. It does not grow the top line and it does not cut the bill, so it waits. We treat it the way our Data and AI practices treat every engagement. We start narrow, prove the value on the exposure that matters most, and expand only when the work has earned it. You keep everything we build, and you always know why a control is there so you can press on it.
We audit your IT, data, and physical footprint and rank exposure by what a real incident would cost the business, not by a generic checklist.
You get a cost- and time-aware plan focused on your few critical gaps first, so the early spend buys down the risk that would hurt the most.
We work inside your team and hand over what we build. When we step back, your people understand the controls well enough to run and defend them.
The gaps stay invisible until a ransom note, a stalled enterprise deal, or an auditor finds them first. The incident is the same either way. What you did before it is the difference.
The unprepared bad day
HOUR 1
Files are encrypting across shared drives. Nobody is sure who to call.
DAY 2
Backups exist but were never tested. The restore fails.
WEEK 1+
Operations still down. Customers and partners start asking questions.
WEEK 3+
Systems rebuilt from scratch. The story is now public.
Nobody had ranked which systems mattered most, so everything became an emergency at once.
The prepared bad day
HOUR 1
The retainer activates. Experienced responders are on the incident within two hours.
DAY 1
Contained. Critical systems restored from backups that were tested in a tabletop.
WEEK 1
Root cause fixed, not patched over. Customers notified with a clear, planned story.
Same attack, different company. The difference was decided months earlier.
Know your true posture
A deep read of your security program across the core domains, each mapped to the frameworks your customers and regulators care about, with a clear picture of where you are strong and where you are exposed.
Why it matters
Spend the next security dollar on the gap that matters, not the one that is loudest.
Prepare for ransomware
We test how well you can prevent, detect, contain, and recover from a ransomware attack, then show you exactly where the chain would break under real pressure.
Why it matters
Find out whether you could recover in days rather than weeks before the ransom note does it for you.
Vet what you inherit
Security review on acquisitions, supply-chain partners, and third-party integrations, so the risk that lives outside your walls does not become yours by surprise.
Why it matters
Know what you are buying, or connecting to, before it becomes your breach.
Give leadership the number
We identify the risks most relevant to your business, put a plausible cost on the harm each one could do, and give leadership a ranked, defensible view to decide against.
Why it matters
Make the security call in the boardroom with numbers behind it, not a gut feeling.
Make the rules real
We write the policies and standard operating procedures your organization actually needs, fitted to your environment, your team, and your regulatory obligations rather than pulled from a template.
Why it matters
Pass audits and survive staff turnover without the practice falling apart.
Rehearse the bad day
We run your team through a realistic incident scenario and watch where the documented plan and the way people actually react come apart.
Why it matters
Find the gaps in your response in a conference room, not in the middle of a live breach.
Know who is aiming at you
Focused analysis of the threats most likely to target an organization like yours, translated into a short list of the defenses worth prioritizing rather than a firehose of feeds.
Why it matters
Point your limited security time at the threats that are actually coming for you.
Attack it on purpose
We probe your most critical systems the way an attacker would and show you exactly how far someone could get and what they could reach along the way.
Why it matters
Close the vulnerabilities and misconfigurations that a real intruder would walk right through.
Test the whole response
We run realistic attacks against your environment, and in purple mode we do it alongside your defenders so they learn to catch it live using the tactics seen in real incidents.
Why it matters
Learn whether your team can actually detect and stop an attack in progress.
Harden the cloud
We review the architecture and configuration of your cloud environment against the ways these platforms are most often exploited, then help you tighten them.
Why it matters
Shrink the cloud attack surface that grew quietly while you were shipping product.
Protect the keys
We assess the identity and Active Directory misconfigurations, weak processes, and known exploitation paths that let a small foothold turn into full control.
Why it matters
Keep one compromised login from becoming the keys to the entire company.
Meridian builds the governed data and AI systems that organizations rely on to make decisions. Securing those systems is a natural part of the same work, so the people who know how your AI reasons are the ones testing whether it can be broken.
Secure what you deploy
We review the architecture, the defenses around your training and reference data, and the applications built on your models to find where they can be manipulated or leaked.
Why it matters
Deploy AI to customers and staff without opening a door you did not know was there.
Break it before they do
We attack your production AI with the techniques unique to these systems, from prompt injection to data extraction, under realistic adversarial conditions.
Why it matters
Learn how your AI fails on your terms, in a test, instead of in a headline.
Put AI on defense
We help you fold AI into the day-to-day work of your security program, from triage to investigation, so your small team covers more ground.
Why it matters
Give a lean security function the reach of a much larger one.
Stop the bleeding
Experienced responders investigate the attack in depth, manage the crisis across the full timeline, and get your operations running again after a breach.
Why it matters
Contain the incident and fix the root cause, instead of patching over it and waiting for the next one.
Have help on standby
A pre-arranged agreement with a guaranteed two-hour response, plus pre-paid hours you can spend on investigations, training, or advisory work as needs shift, so the help is already lined up.
Why it matters
Cut the hours between the first alarm and expert hands on the problem.
Check for a hidden guest
We hunt for evidence of past or ongoing compromise in your environment, judge your future risk from your current hygiene, and strengthen how you would respond.
Why it matters
Find an attacker who is already inside before they choose their moment.
Control the story
We build the communications plan that protects your stakeholders and your brand during an incident, including playbooks that account for disclosure and notification requirements.
Why it matters
Keep a bad day from becoming a lasting hit to trust and reputation.
Leadership on demand
A senior security lead embedded part-time with your team to own strategy, set priorities, and answer to the board, without the cost or lead time of a full-time hire.
Why it matters
Get executive-level security judgment at the stage where a wrong call is expensive and a full-time hire is premature.
Watch it in production
We help you design monitoring around the threats that matter, tune it against real attacker behavior, and work alongside your team or your provider so alerts turn into action.
Why it matters
Turn a wall of alerts into the few that mean something, and a response when they fire.
Raise the human firewall
Practical, current training for your team, built around the phishing and social-engineering tactics actually being used against companies like yours rather than stale annual slides.
Why it matters
Close the gap that most breaches still walk through, which is a person who was never taught what to watch for.
Test the front door
We assess how someone could reach your people, servers, and stock in person, from tailgating and badge cloning to unmonitored entry points and blind spots, and show you where the building lets you down.
Why it matters
Find the way in that a determined intruder would actually use, before they do.
Control who gets in
We design, install, and manage badge access and camera systems fitted to your sites, so you decide who enters which spaces and keep a clear record of what happened and when.
Why it matters
Control who reaches what matters, and have the footage when an incident turns into a question of who and how.
Frameworks we work across
We map our work to the frameworks that matter in your industry and help you meet and certify against them. Recognized standards, applied to your environment rather than pasted in.
