Cybersecurity Services in Atlanta
NetSys provides cybersecurity services to businesses in Atlanta: 24/7 managed detection and response on every device, identity and email protection across Microsoft 365, vulnerability scanning, staff training and immutable backups, with an engineer acting on alerts rather than forwarding them. Atlanta is served from Brooklyn, in the same Eastern time zone. Monitoring, help desk and remediation run remotely around the clock from Brooklyn. On-site commitments are arranged in advance and sized to the engagement. Most clients run between 10 and 75 seats, and every agreement is month to month.
The short answer
NetSys provides cybersecurity to businesses in Atlanta: ThreatDown managed detection and response on every device, multifactor authentication and Conditional Access across Microsoft 365, Barracuda email protection, Rapid7 vulnerability scanning, security awareness training and immutable backups with tested restores. Delivery is remote-first from Brooklyn, and on-site commitments are arranged in advance and sized to the engagement, up to a dedicated engineer with a drive time generally under an hour where regular presence is part of the scope. Most clients run between 10 and 75 seats, and every agreement is month to month.
How cybersecurity is delivered in Atlanta
Atlanta is served from Brooklyn, in the same Eastern time zone. Monitoring, help desk and remediation run remotely around the clock from Brooklyn. On-site commitments outside the tri-state area are arranged in advance and sized to the engagement: a mostly remote engagement needs no dedicated on-site engineer, while an engagement that calls for regular presence, such as vCISO work with someone on site two days a week, gets a dedicated engineer whose drive time is generally under an hour, depending on where that engineer and your office are. Hardware ships pre-configured, so most projects need no visit at all. The buildings decide a lot of the design. Midtown and Buckhead towers have carrier choice, but Alpharetta and Perimeter office parks are often single-circuit Comcast or AT&T, and the metro's payment-processing concentration makes PCI DSS a working requirement for more businesses than expect it. The carriers we see most in Atlanta are AT&T Business Fiber, Comcast Business and Google Fiber, and the failover design starts with which of them actually reach your building.
Who cybersecurity in Atlanta is built for
Most of our Atlanta work sits in Midtown, Buckhead, the Perimeter, Alpharetta and Downtown: logistics and supply-chain companies on Manhattan Active, fintech and payments firms on Salesforce, medical practices on eClinicalWorks, law firms on NetDocuments, film and media businesses on Frame.io, and real estate firms on Yardi. Each carries its own compliance load, which the section below covers, and each has a line-of-business vendor we coordinate with rather than work around. Companies with an internal IT person fit too; in that case we supply the monitoring, the security stack and the after-hours coverage behind them, and they keep their projects.
What tends to go wrong in Atlanta
Two things shape the continuity design here. First, the weather and the grid: summer storm and ice-storm power outages are the recurring risk, so UPS runtime, cellular failover and off-site backups are standard. Second, the attacks that actually land locally are ordinary ones, and the public record shows how they go: the March 2018 SamSam ransomware attack on the City of Atlanta, which cost the city an estimated $17 million to recover from, and the January 2024 LockBit attack on Fulton County. The controls in the next section are the ones that would have changed those stories.
Cybersecurity in Atlanta: what NetSys delivers
Detection and response
- ThreatDown managed detection and response with EDR agents on every workstation, laptop and server, monitored 24/7
- Microsoft Defender for Business and Rapid7 InsightIDR telemetry from identities, email and endpoints, with a person acting on alerts
- Isolation of a compromised device in real time, with an engineer on the case rather than a ticket in a queue
- Incident investigation and a written timeline for leadership, counsel and your insurer
Identity and email
- Entra ID Conditional Access and multifactor authentication across Microsoft 365, with legacy authentication switched off
- Privileged access and privileged identity management so admin rights are granted just in time and removed afterwards
- Barracuda Email Protection in front of every mailbox, with SPF, DKIM and DMARC enforced
- KnowBe4 security awareness training with simulated phishing built from the lures your industry receives
Exposure and recovery
- Rapid7 InsightVM vulnerability scanning on a schedule, with findings fixed rather than filed
- Cisco Meraki or Fortinet firewall management, segmentation and DNS filtering on office and remote devices
- Immutable backups through Datto SIRIS or Veeam, with restores tested and documented
- The free remote external penetration test, limited to available information and the external scope agreed with you
A 75-person film or media busines in the Perimeter
The specific engagements behind this profile are under NDA, so it is written as a generalization rather than a named client. Our published, client-approved outcomes are in case studies.
A 75-seat film and media businesses in the Perimeter that handles regulated data in Frame.io across the office and remote staff on home Wi-Fi. A former employee's account was still active six months after they left. Email protection is whatever Microsoft ships by default, DMARC was never set up, the Google Fiber firewall is a consumer router, and the last security training anyone remembers was a poster.
- KnowBe4 rolled out with a baseline phishing test in week one and training on a recurring schedule, aimed at the lures the industry actually receives
- Vendor questionnaire answered from the documented controls, with the evidence attached rather than promised
- Free remote external penetration test limited to information available to NetSys and the external scope agreed with the business; internal review and remediation scoped separately
- Barracuda Email Protection placed ahead of the mailboxes and SPF, DKIM and DMARC corrected so the domain can no longer be spoofed, with a callback rule adopted for any change in payment instructions
- Cisco Meraki firewall installed with intrusion prevention, geo-blocking, segmentation between finance, servers, printers and guests, and DNS filtering on every device
- A written incident response plan with named owners, the insurer's hotline and counsel's contact, tested on a tabletop exercise
Every device is watched by a team that responds, every account sits behind multifactor authentication and Conditional Access, the domain cannot be spoofed and the backups restore. The questionnaire gets answered from documentation. Month to month, like every NetSys agreement.
Firewall, antivirus and maintenance for a five-person office
A five-person office needed the basics done properly rather than an enterprise stack. NetSys replaced the internet provider's router with a business-grade firewall configured with sensible rules, secure remote access and logging, deployed managed antivirus on every machine with updates and alerts handled centrally, and put patching, backup checks and health reviews on a schedule. The agreement covers what the office needs and nothing it does not, month to month. No outcome figures were measured for publication.
Compliance in Atlanta: O.C.G.A. § 10-1-912 and what sits on top of it
If you hold personal information on a resident of Georgia, Georgia's breach-notification statute (O.C.G.A. § 10-1-912) requires notice to affected residents in the most expedient time possible after a breach of unencrypted personal information. Georgia has no comprehensive privacy statute, so for most Atlanta businesses the operative rules come from HIPAA, PCI DSS, GLBA, cyber insurers and enterprise customers' vendor questionnaires. Healthcare practices carry HIPAA, logistics and fintech firms answer to customer audits, and payment-card volume through the region's processors makes PCI DSS a working requirement. The security service is built to produce the evidence those rules ask for: multifactor authentication and Conditional Access reports, endpoint detection coverage, vulnerability scan results, backup restore records and a tested incident response plan. Most firms we take over have none of it documented, which is the part that matters if you ever have to demonstrate compliance, so the documentation is built during onboarding rather than sold as a separate project.
What cybersecurity costs in Atlanta
Cybersecurity is priced per user per month when it runs as an ongoing service, and per project for an assessment or a remediation. What moves the number: how many devices and identities are in scope, whether 24/7 response is needed beyond monitoring, which compliance standard the evidence has to satisfy, and whether the Microsoft 365 tenant is already on Business Premium or the security tooling comes from us. The free external penetration test costs nothing and runs remotely before any of that. Our managed IT pricing page explains how the fee is built.
Who this fits, and who it does not
Best fit: businesses with enough people, money movement or regulated data that a breach would hurt, and no security team of their own: professional practices, healthcare groups, importers, financial firms, nonprofits and agencies holding client credentials. Companies with an internal IT person fit as a co-managed arrangement.
Not a fit: organizations that want a security product installed and left alone. The service is monitored, reviewed and reported monthly, and it changes the way administrators, finance staff and vendors work. If that is not wanted, a tool purchase serves better than an engagement.

Cybersecurity in Atlanta: FAQs
What is managed detection and response, and do we need it?
MDR puts an EDR agent on every device and a 24/7 team behind it that isolates a compromised machine and investigates, rather than an antivirus that quarantines a file and moves on. Cyber insurers now ask for it by name, which is the practical reason most businesses in Atlanta end up with it.
Can you work alongside our internal IT person?
Yes. In a co-managed arrangement your person keeps the day-to-day and we run monitoring, the security stack, vulnerability management and after-hours response, with the split written into the agreement.
Do we need a security assessment before signing up?
The free external test is where most engagements start. A fuller assessment of the tenant, devices, network and backups is scoped separately and produces a prioritized fix list that becomes the first ninety days of the service.
Do you have an office in Atlanta?
Our office is in Brooklyn, NY. Atlanta is served from Brooklyn, in the same Eastern time zone. Outside the tri-state area the on-site arrangement is agreed before the engagement starts and sized to what it needs: none for a mostly remote account, and a dedicated engineer, generally within an hour's drive, where regular presence such as vCISO work with someone on site two days a week is part of the scope. The proposal states that arrangement, coverage hours and any travel in writing, and the agreement runs month to month.
What does Georgia law require after a data breach?
O.C.G.A. § 10-1-912 requires notice to affected residents in the most expedient time possible after a breach of unencrypted personal information. Georgia has no comprehensive privacy law, so the standards a business is actually held to usually come from HIPAA, PCI DSS, insurers and customer contracts.
See what an attacker sees before they do.
The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. Internal reviews and ongoing security management are scoped separately.
