Managed SIEM Services for Small Business

Managed SIEM services: every log collected, kept and actually read

A SIEM gathers the logs from your laptops, cloud accounts, firewalls and sign-ins into one place, keeps them for as long as you need, and flags patterns that look like an attack. Upfortify runs the platform for you: we connect your sources, tune the rules, manage retention and hand real alerts to analysts.

A SIEM is the log platform, the SOC is the people

These two get mixed up, so here is the split. A SIEM (security information and event management) is technology: it pulls logs from every system you run, keeps them in one searchable place and correlates events to spot attacks no single system would notice on its own. A SOC is the team that investigates what the SIEM raises and acts on it. This page covers the platform. SOC as a service covers the people who watch it.

You need both. Logs nobody reads don’t stop anything, and analysts without centralized logs can’t see the whole attack.

Why remote teams need centralized logs

When everyone sat in one office, a lot of activity crossed one firewall. A remote team’s activity is scattered across home networks, cloud apps and identity providers, and each one keeps its own logs in its own console, often only for a short window. An attacker who signs in from abroad, creates a mailbox forwarding rule and downloads a client folder leaves traces in three different places. A SIEM puts those traces side by side, in order, so the pattern is obvious.

Centralized logs also matter after the fact. When something does go wrong, investigators, insurers and sometimes regulators ask what happened and when. If the evidence aged out of a cloud console after 30 days, nobody can answer.

What our managed SIEM includes

Log source onboarding. We inventory your systems and connect the ones that matter: Microsoft 365 or Google Workspace, identity, endpoints, firewalls, VPNs, cloud platforms and key business apps.
Correlation and detection rules. Rules that link related events across sources, mapped to common attacker techniques, and updated as new ones appear.
Tuning. Known-good activity is suppressed so analysts spend their time on alerts that could be real.
Retention you choose. Log storage set to what your industry rules, insurer or contracts require, with the setting documented.
Integrity and access control. Logs are stored where an attacker on your network can’t quietly edit or delete them, and access to them is limited and recorded.
Health monitoring. If a log source goes quiet, we notice. A silent source is often the first sign something was switched off.
Reports you can hand over. Plain-English monthly summaries, plus log evidence pulled on request for audits, insurance questionnaires or investigations.

Vendor-neutral by design

We pick and run the SIEM platform that fits your environment, your data location needs and your budget, rather than forcing one product on every client. Whatever runs underneath, you get the same outcomes: the right sources connected, alerts tuned, retention documented and analysts on the other end. If you already own a SIEM license, we can take over operating it.

From scattered logs to a clear picture in four moves

Connect your sources

We map your systems and stream their logs into one platform, starting with sign-ins, email and endpoints.

Tune the noise out

Detection rules are adjusted to your environment so routine activity stops raising alarms.

Watch and correlate

Related events across systems are linked together, and real alerts go straight to our analysts.

Keep the evidence

Logs are retained for your required period and are ready when an auditor, insurer or investigator asks.

Logging the AI tools your team uses

AI tools create their own trail: sign-ins to chat assistants, new app permissions on mailboxes and drives, and large uploads to unapproved services. Feeding those events into the SIEM shows where company data is going and supports your AI governance program.

Frequently asked questions

What is a managed SIEM?

SIEM stands for security information and event management. It is the platform that collects logs from across your environment, stores them and looks for suspicious patterns. A managed SIEM means a provider sets it up, connects your log sources, tunes the detection rules and manages storage, so you get the visibility without running the system yourself.

What's the difference between a SIEM and a SOC?

The SIEM is the technology: it collects and correlates logs and raises alerts. The SOC is the people who investigate those alerts and respond. You need both. A SIEM with nobody reading its alerts is an expensive archive, and a SOC without centralized logs is working half blind. Our SOC as a service runs on top of the SIEM we manage.

How long do you keep our logs?

As long as your requirements call for. Retention is set per client to match what your industry rules, cyber insurer, customer contracts or internal policy require. For example, PCI DSS calls for 12 months of audit log history with the last three months readily available. We document the retention setting so you can show it during an audit or review.

Which systems can you collect logs from?

Typically Microsoft 365 or Google Workspace, identity providers, endpoint protection, firewalls and VPNs, cloud platforms like AWS and Azure, and key business applications. During onboarding we inventory your systems and agree which ones feed the SIEM first, starting with the sources attackers abuse most: sign-ins, email and endpoints.

Do we need a SIEM for compliance?

Many frameworks expect you to collect, protect and review audit logs, including PCI DSS, HIPAA's audit control requirements, the CJIS Security Policy and SOC 2. A managed SIEM is a common way to meet the logging part of those expectations. It supports compliance work; it does not by itself make you compliant.

Will a SIEM bury us in alerts?

Not if it's tuned. An untuned SIEM is noisy, which is why most small teams give up on running one themselves. We tune rules to your environment, suppress known-good activity and send only alerts worth a person's time to our analysts. You hear about the ones that need you.
