QuantM is a cybersecurity company serving Markham businesses and the rest of York Region. We provide 24/7 human-led managed detection and response (MDR): analysts who watch Microsoft 365, email, identities and endpoints, and act when something looks wrong. It is built for owners who got the question from a customer questionnaire, an insurance renewal or a phishing near-miss: is anyone actually watching our Microsoft 365, email and user accounts, and should that be QuantM?
We are a cybersecurity-focused MDR and governance partner, not a general IT provider. Markham technology firms, manufacturers, financial and professional services teams and health and life sciences organizations can use QuantM as the security monitoring layer beside their current IT support. Median MDR triage is under 5 minutes, and our email protection blocks 99.4% of phishing. The fastest way to find out where you stand is a free 15-minute M365 Posture Review.
Markham runs on a dense mix of technology companies, engineering and manufacturing operations, and professional offices along Highway 7, Woodbine Avenue and the Highway 404 and 407 corridors. Many of these teams are growing fast, adopting new SaaS tools as they go, and selling to larger customers who ask hard questions about how data is protected.
That combination creates a predictable gap. Microsoft 365 and cloud accounts hold the contracts, designs, source material and client records, yet the day-to-day IT contract usually covers support, devices and patching, not someone investigating a suspicious sign-in at 2 a.m. QuantM fills that gap with analysts who review alerts around the clock and take the containment actions you have pre-approved against account takeover, business email compromise and endpoint threats.
Many Markham firms compare a long list of general IT providers before they find a security specialist. The difference to look for is simple: who is monitoring, who investigates, and who acts. That is the work QuantM does.
For companies on a growth path, there is a second benefit. Buyers, partners and insurers increasingly ask to see how security is run, not just whether a tool is installed. Continuous monitoring, agreed escalation contacts and a written report after incidents give a Markham owner something concrete to point to, and they give your own team time back to focus on the business instead of chasing alerts.
QuantM has one customer-facing office, at 100 King Street West in Toronto. We deliver monitoring and response to Markham remotely.
Tech teams live in Microsoft 365, cloud consoles and collaboration tools, and a single compromised account can expose product plans, customer data or code access. QuantM monitors identity and cloud sign-in behaviour so unusual access is investigated, not just logged. It also helps teams answer the enterprise security questionnaires that large customers send during procurement.
Engineering and production firms in the Markham industrial areas rely on email-driven supply chains, shared drives full of drawings, and endpoints that cannot afford downtime. Fraudulent invoices and look-alike supplier emails are a common route in. QuantM monitors email, identities and endpoints and escalates early so a bad day stays a small one.
Accounting, wealth and advisory practices handle client financial records and wire instructions, which makes email compromise an obvious target. QuantM watches mailbox rules, risky sign-ins and impersonation attempts around the clock. Incident reports are written in plain language so you can explain to a client or an insurer what was monitored and what happened.
Clinics, labs and research-focused companies protect sensitive personal and proprietary information, often on a small IT footprint. QuantM provides continuous monitoring of the accounts and endpoints that touch that information and helps prepare the evidence privacy and partner reviews ask for. It supports your compliance work and does not replace your own responsibilities.
Law firms and consultancies hold privileged files and client confidences in email and shared storage. A phishing near-miss or a client questionnaire is often the first sign that monitoring needs an owner. QuantM adds that owner without disturbing how your lawyers and consultants already work.
Getting started is deliberately light. You do not need to replace your IT provider or rebuild your environment, and the connection work is planned with your IT contact so people can keep working as usual.
A short, free call to look at how your Microsoft 365 tenant, email and identity settings stand today, so you leave knowing where the gaps are.
We agree what is covered, then work with your IT contact to connect the Microsoft 365, identity, email and endpoint sources that fall in scope.
Analysts review alerts day and night, including weekends. Median MDR triage is under 5 minutes.
When an alert is real, we take the containment actions you pre-approved, tell you what to do next, and send a written report afterward.
If you are comparing IT security companies in Markham, ask each one to name the exact sources it watches and who reviews the alerts. This is the QuantM list for a typical Markham tenant.
Many Markham businesses already rely on an IT provider or an internal admin, and that relationship should stay. QuantM sits next to it as the security layer and covers detection, investigation and response coordination. Your provider keeps the helpdesk, devices and daily administration.
Before monitoring starts we write down who does what, including who we contact overnight and which actions we may take. That gives you one clear line of responsibility for security without a contract swap. If your provider already resells security tools, we can review what they cover and what they do not, then fill the gap rather than duplicate it. Markham MDR does not have to mean starting over.
It monitors your systems for attacks and acts on them. QuantM provides 24/7 human-led MDR across Microsoft 365, email, identities and endpoints, so suspicious activity is investigated and escalated, not just recorded.
Your IT provider keeps systems running. QuantM focuses only on security monitoring and response. Most clients keep their current provider and add QuantM as the security layer.
Yes. Start with the free 15-minute M365 Posture Review. We will show where your Microsoft 365 setup stands and how continuous monitoring answers the questions that customers and insurers ask. We help you prepare, but we do not promise a specific outcome.
It helps you prepare. Insurers often ask whether anyone monitors your environment, and managed detection and response gives you a clear answer to that question. Coverage decisions remain with your insurer, so we suggest bringing your renewal questions to the posture review and we will map them to what is monitored.
Median MDR triage is under 5 minutes. Analysts work around the clock, and when an alert is real we take the containment actions you pre-approved and tell you what to do next.
Microsoft 365 and Entra ID are the usual starting point, along with email, endpoints and cloud accounts. We confirm scope during the posture review so you know exactly what is monitored, and we flag anything that falls outside it so nothing is assumed.
MDR is managed detection and response: a team of analysts monitors your environment and responds to threats. Markham companies with growing teams often want that coverage without hiring a security staff of their own, because building a round-the-clock team in-house is hard to justify at their size.
Our email protection blocks 99.4% of phishing. No control stops everything, which is why people also watch for what gets through.
Our customer-facing office is at 100 King Street West in Toronto. We deliver monitoring and response to Markham remotely.
No. Monitoring follows your Microsoft 365 tenant, identities and devices, not an office address. Sign-ins from customer sites, hotels and home networks are reviewed the same way, and analysts escalate the ones that look wrong.
The first step is free: a 15-minute M365 Posture Review. Pricing for ongoing service depends on scope, so we discuss it after we understand your environment.
The free M365 Posture Review is a focused 15-minute look at how your Microsoft 365 environment is protected and who is watching it.
